ELECOM HUGE Trackball Mouse, Wired, Finger-Operated, 8-Button Function, Palm Rest Attached, 52mm Smooth Red Ball Windows11, macOS (M-HT1URBK)

Update (7/13/2023): I purchased an alternative that seemed close in 'stature' to this mouse because I wanted Bluetooth connectivity, as mentioned earlier for my notebook(s) in case I travel. In general I wanted to just use one mouse. The idea is I use it on my PC (using usb dongle) and then BT elsewhere. Anyway, I got a Nulea, which is nice but it still doesn't hold a flame to this mouse. The back of the Nulea is almost slippery compared to the HUGE and is not as wide, thus, it just doesn't feel as comfortable. My hand sort of just wants to slide off the surface, which makes the material they popped on the HUGE pretty thoughtful. Update (5/10/2023): This has remained my absolute favorite mouse. Wear and tear is so very low even though I use it daily. All I can hope for now is that they make an almost identical updated version, but wireless AND Bluetooth and maybe even a plug-in for a wire so I can buy one to use with my notebook(s), basically a Deft Pro version of this mouse. Again, I personally love and highly recommend this device. This is THE PERFECT finger trackball mouse for bigger hands (and even perhaps, for any hands). Initial Review: I'm one of the unfortunate few index trackball addicts. I cannot use a regular mouse for very long and I certainly can't use a regular mouse for any sort of gaming. That being said, what started me on this terrible journey was a Logitech Marble Trackman - that trusty trackball that's still around. Shortly after succumbing to the trackball, I moved on from that to a Logitech Cordless Trackman Optical, this is where things went wrong. It was for me, the perfect device. A trackball mouse that just seemed to fit perfectly in my right hand. It had a few extra buttons that came in handy for games. My first lasted 2 years and the second lasted roughly the same except just before this one died Logitech decided to discontinue the product - oh, %^#t. I went through phases of tech grief, which are sort of similar to regular grief. I denied that the product was discontinued and convinced myself that the product was cycling, which is when they sometimes discontinue the product and re-release it in a few months with different colors or a different name. This did not happen. I then became quite angry, which I know is quite silly but hey, it happened - because I felt betrayed by the company. How can you, as a company, release 1001 different models of the same mouse but just 1 very, very, very basic model to cater to index finger trackball users? I then entered the bargaining phase, which is where the tech part of this comes in. I took to their forum, Twitter, Facebook, anywhere I figured I could nudge the company into getting the idea that we (index finger mouse users) exist, enough so to at least bring another model to market. I came pretty close to publicly begging. After months and not a peep from the company, I became sad - depressed isn't the word I'd use, again, this is not real grief, just tech grief. I felt sad because I felt really uncomfortable and out of place using a regular mouse and nothing else was working for me. I tried several from various companies like Kensington and the thumb trackball from Logitech (which I cannot use, whatsoever). Finally came acceptance. A slap in the face recently is that the company introduced a new thumb trackball, as if their M570 weren't enough, they released the sleek MX Ergo Plus - Ouch. I bought a new Logitech Trackball, the basic one, you know and that was that for some time. Enter Elecom, a foreign company that doesn't seem to be on the radar yet. One day I decided to do another search for trackball mice and I discovered the Deft or EX-G series, whatever they call it. I bought it and it turned out to be a great cordless Trackball, however, the ball never quite felt right and the shape was just off enough to make it, not quite a gamer mouse for me, though I could use it for everyday PCing, etc. Finally, finally, I get what I want/need. They've released a larger version that is, perfect, for what it's worth. I can't really explain how great it feels so I'll say this. I wrote those previous anecdotes for a reason, so you could/can identify with me. If you've ever used that darn Logitech Cordless Optical Trackman OR the Microsoft Trackball Explorer, which is very similar in feel, then this is it, folks, this is the trackball for you. At first, it feels a bit large, too big in fact - but give it a few, just like the Trackball addiction sneaking up on us, the device eventually becomes just right. I don't quite remember how my hand was when I used the previous devices but I think the most jarring difference is that you won't have to contort your ring finger to right-click, as the buttons lay right under your hand in a naturally open position. The top of the device is large and there's soft padding so you literally just lay your hand down on top of it, it's very comfortable. There are some extra buttons that I haven't figured out how to use since I haven't read the manual (3 function buttons) but you get the staple of an advanced Trackball otherwise, you get a clickable scroll wheel in addition to 2 clickable buttons (forward/backward for browsers) just above it. All of these tend to work universally and are easily bindable in games. The left button is under the scroll wheel in a really great position, IMHO, as my thumb sits right there. The 3rd function button lies beside the right clicker. There's a switch on the device that seems to increase trackball speed manually vs. through software. So far, it's a fantastic device. I got the corded version and am seriously considering buying 2 or 3 more and just putting them away, just in case. I'm giving it some time to see what if anything happens to the device after months of use. Thank you Elecom and Thank you seller and Amazon! Just came back to say that after many months, the mouse still works perfectly. I own 2 now. 1 for my main system and another for my work system. I'm going to buy 2 more as I mentioned before to put away, just in case Elecom decides to call it quits on production. I also have my eye on the Bluetooth model that I will likely use with my mobile devices - I'll see. The HUGE is so great, I'm not sure I want to change the formula.

Edit/update - 04/05/2024 My first Elecom Huge is still kicking, at this point something like 3.5 years later. Great mouse, fantastic ergonomics. The second one went faulty last year, but still lasted well over 3 years. Unfortunately though, I've bought more since (for use at other workstations) and the quality has gone way downhill. One I bought only lasted 2-3 months before getting the dreaded "double click" failure, when the mouse double clicks frequently when only clicked once. It's a failure of the Omron switches used for the left mouse button. I threw that one out thinking it was a fluke, but I bought another in November of 2023, and already it was failing the same way by late February 2024, didn't survive for even four months. I notice the new mice say "Made in Taiwan" on the bottom, whereas the original that still works after 3+ years was "Made in China." Beyond that I can't say what differences there are. I haven't disassembled the original since it still works. Thankfully, I've been able to salvage the defective mouse by desoldering the faulty Omron switch and replacing it with a Kailh GM2.0, but I fully understand folks not wanting to do that. I didn't want to do that, but I refuse to spend another $50 on yet another likely defective unit (they're all using the same Chinese Omron switch), and this fix worked with a bit of time and effort. 4-pack of the Kailh switches is only $6 or $7. ========================== I've been a Logitech Marble Mouse user for years. I was kind of on the fence on this mouse, but as soon as I got my hands on it and used it for a day, I boxed up my Marble Mouse and bought a second Elecom Huge for use at work. It's so comfortable, buttons are customizable with software, and it's got more than enough buttons and a scroll wheel with rocker. I do have concerns about how well the memory foam cushion will hold up over time, but so far I've been using it for over six weeks with no issues. It's so much better than my old mouse. It's definitely not for everyone, but Elecom has quite a few offerings in different sizes and should have a trackball for any size hand.

This review is for the ELECOM M-HT1URBK wired version on Windows. I don’t think there is any perfect track ball. Everyone’s hands are different in size and dexterity, to say nothing of right vs left handedness. This trackball is firmly in the right hand, medium sized hand camp. And, this Elecom M-HT1URBK is a mixed bag of very good and not so good. **So first the hardware: It is described as an 8 button track ball, but it really has 10 buttons or switches. The scroll wheel has three, Tilt Up, Tilt Down, and Push In, along with scroll function. Elecom makes several trackballs, and they rightly are divided into “thumb operation” and “forefinger operation.” This is the forefinger type which I prefer. Compared to some other trackballs in the field I find it well built. The anti-skid pads on the bottom are just OK. They work if really clean, the slightest bit of dust and the trackball skids around easily. The soft palm rest is OK now, but time will tell if it gets sticky or degrades with hand oil as most others do. As for the trackball itself, I find it a good size at 52mm. It rides on three ruby red nubs. Those nubs stand a bit higher in the Elecom than other manufacturers. For example my Kensington SlimBlade’s ruby nubs are almost flush with the ball housing. With Elecom’s being higher it takes a bit longer for the ball to gum-up and get sticky with debris. Other reviewers have commented on the not so smooth performance of the trackball itself. I don’t find that an issue. I have a collection of just about every track ball made, going back to the early days of computer GUIs. The early ones were essentially, an upside down mouse. They used steel wheels to track movement and were really rough. Modern trackballs such as this Elecom use reflected light off the ball to track movement. However I find that every modern trackball has to be ‘treated’ out of the box. Here is my method: Get some Engleside Old Fashioned Kitchen Wax & Cleaner. ASIN: B005WW1JF6. Give the ball a good washing with liquid dish detergent. Dry it completely and then use the Engleside to wax it up. Wax it twice, use a soft cotton rag, and be sure to buff to dry between applications. If you do this you will have no complaints about smooth movement. Do it as routine maintenance. Elecom claims on their website they use Omron switches. I have not taken this trackball apart to verify that, but I can say some of the buttons have a very clear and easy click. But, not all the buttons click with the same force. For example the LMB really only clicks well in the forward most finger position. As you move back on the button the force changes to where it won’t click at all. This does tend to slow me down when working, as I have to find the sweet spot to click. The thing is, that is just opposite of the so-called Button #5. The rear of the button is easier to click than the front, go figure. And the other thing about that most used LMB is that it is positioned a bit under the scroll wheel, so I have had to disable the “Scroll In” button as I sometimes hit them both with my fat thumb. Also, I find the scroll wheel to be too far to the rear of the housing. I have to bend my thumb a bit more than I would like. Lastly the “R” or Right button needs to be widened near the top to cover the blank area at about one or two o’clock on the ball. If the “R” button were wider there, it would facilitate Right-Click Drag. In fact I have assigned “Right Click” also to “F2" to help with drag. There is a switch near the base that allows one to switch the pointer resolution between 500/1000/1500. An LED will blink once for the first position, twice for the second position, and three times for the third position. That helps to verify the switch position. **On to the software: Go to the manufacturer’s website and download the latest software. The M-HT1URBK is not currently listed under “Products>Trackball mouse.” Just search for it and it will come up. This review is for the Mouse Assistant for Windows v5.2.00.000 which is current as of this writing. BTW Elecom, it is not a “trackball mouse” it is a trackball pointer, but that is a rant for another time. And, there is a downloadable 23 page PDF manual in English, and some other languages. The install routine is well behaved and requires a reboot. There is no “About” button or check for update button in the software, so it is hard to know if one is running the latest version. The software did recognize the attached trackball and put up the correct picture on the “Allocate button function” tab. There are 46 plus Off assignable functions for each of the ten buttons. And if one fails to assign the two most necessary functions (i.e. for Windows-right and left click) the software puts up a warning box (see pix) and will force one to assign Left Click to a button. As good as that is, inexplicably it ignores the just as important Right Click. However, software labels for the buttons don’t match what are on the trackball. E.g. the trackball button Fn1 is labeled “Button 6:” in the software. If the user clicks on the list box for Button 6, the corresponding button on the trackball picture lights up. But, it does not work in reverse. One should be able to click on the button in the picture and have corresponding assignments come up. Also the scroll wheel tilt is labeled in the software “Tilt left:” and “Tilt right:” but it really should be labeled “Tilt up:” and “Tilt down:” Left and Right is an assignable function, not what one does with a finger. There are other labels that don’t match. If the software can sense the specific model of trackball, it should be able to use the correct labels. As it is, it is just an awkward UI. One can create custom profiles; save and name them. The software defaults to putting an icon in the notification area so it is easy to switch between profiles. There is a feature called “flying scroll” [with apologies to Jay Ward, not Rocky the Flying Squirrel] It is essentially an auto scroll function, and will take some playing with to match your reading speed, but useful, nevertheless. There is a new for this version “Presentation mode” in the current software which the manual hasn’t caught up with yet. I played with it a bit, and it will take some work to see what it does. I’m sure an updated manual would help this. The last tab is for gesture functions. Just be careful of conflicts with Win10 gestures. So all in all there is a learning curve to the feel and the customization for any one individual’s use, but I’m glad I have it and look forward to when it will become more intuitive.

I have had the wired HUGE for a 6 months in an IT professional environment and use it for my main mouse for 8 hours a day. I bought this to “try” a trackball, save some desk space, and possibly help my wrist relax a bit. I am coming from a Razer Copperhead, a typically shaped mouse with multiple reprogrammable buttons. I love the HUGE. It is very comfortable for office use. It is very fast to navigate with. I am 6’1” and have “spider” hands; long and skinny. I usually end up positioning my hand far more forward than I’d normally expect, with the ball resting on the second bones of my index, middle, and ring finger. My wrist has felt better with this than a normal mouse. The button positions are odd at first, but you adapt quickly. I actually have become accustomed to right clicking with my pinky. The other programmable buttons are convenient to program in the application. I’ve attached images of all the default options for the buttons, but the “Arbitrary Key” can let you do pretty much anything. I usually leave the sensitivity on the maximum. It took about 2 days to get used to it. The funny thing is now when other people come to use my computer, they try to use it and go “woah…this is too sensitive” and can’t find the click (thumb) button. I call it self-encrypting hardware. The driver software I’ve been using with Windows 10 is titled “mouse_driver_ma516000” if anyone has issues finding it. I will definitely get one of these again if something happens to this one. UPDATED 24 July 2019 - Still have it, dispute moving 2 jobs. I LOVE IT STILL. It keeps my wrist happy and is useful for general computing, CAD, and business productivity. I will be buying another for my house....and the smaller wireless on for when I'm on the road.

I have recurring problems with RSI from my mouse usage at work. It got worse recently so I decided to invest first in a vertical mouse, but I didn't feel it made that much of a difference. I did some online research and quickly turned my attention to index finger driven trackballs (not thumb), particularly the Kensingtons which looked promissing. After some more review reading I discovered this beast. I was surprised that the package arrived a couple of days early (US to EU shipping). A few notes to the software. I googled "elecom huge driver" and quickly found the ELECOM Mouse Assistant. Even though I downloaded with the english language link and the installer was in english, the context menu was still in japanese :-D By trial and error I opened the settings app and found the dropdown for changing the language (right-click the icon in the tray, choose the 3rd menu item, the dropdown is in the bottom left corner of the window). Other than that the software seems to work fine. Now the unit itself. (disclaimer: I have tried a few other trackballs shortly, but this is the first one I own) I tried all 3 sensitivity settings and all of them are OK. I have yet to decide which one I'll keep using. Trackball size is nice and I think it rolls pretty smoothly (from the reviews I expected worse). I think the accuracy is pretty good as is, but precisely hitting small buttons (closing browser windows, etc.) is kinda hard for me (maybe I will just get used to it). Some reviewers said they (had to) replaced the artificial ruby balls on which the ball rolls. I was convinced that I will do that too, but now that I've tried it I think I'll just use it for a few days and see how it goes. Maybe I'll just end up doing it anyway just to see if it can be even better. Like I said I still need to get used to the trackball experience. Button positioning. I find that so far it's kinda hard for me to roll the ball nicely and left-click without "interrupting my flow" with the ball. I will see how that goes. All the buttons are sort of where your fingers already are, but it takes some getting used to and feeling out the positions so you won't have to look. I'll probably map middle click to some other unused button cause side-clicking the wheel feels a little impractical. Hand rest. I read positive and negative reviews on this and I must say that I don't really like it as it is. Not sure if it is designed for smaller asian hands or something (do they have smaller hands?). When I put my hand on it so that I can comfortably reach the buttons and the scrollwheel, my hand is forced to point a little upwards and that feels uncomfortable. When I however move it forward to lean my wrist a little higher (which feels better), I can no longer comfortably reach the buttons and wheel. I think I'll have to diy some tiny pillow/padding/thing so that my hand can rest on the "hump" in the middle and not my lower palm/wrist which makes my RSI symptoms worse. I will experiment with that. Overall I am excited and I hope I can further improve the experience and find the best way to use this...and get rid of my RSI symptoms... Update: I replaced the artificial ruby balls with ceramic ones (2.5mm) as suggested by other users and I have to say the ball does roll a little smoother. The wired version has one screw hidden approx. in the center under the black sticker so you have to cut through to get to it. Other than that it's rather easy. After a few days my accuracy with the trackball has already improved. I even tried gaming with it and the results are not terrible.

I just realized that the review I posted is being applied to 2 different mice that I've purchased. So, I'm going to add my review for both here instead. Make: Elecom Model: Deft Pro Type: Index-operated trackball mouse Ergonomics: Angled to the right, nice big left button, right-click is a little small. Other buttons nicely sized and well placed. The slight angle to the right does allow for the wrist bone to be the main point of contact on the table, but it isn't significant as there is still a bit of the base of the palm on the table too. Movement: The trackball is a very pleasant medium weight. I like how the weight makes it feel like a little more quality without itself being a problem with motion. However, the ball does stick on the ruby bearings just like the Huge. Fortunately, because the ball weight is slower, the coefficient of friction is lower so that it takes less effort to get the ball rolling. But, it still does cause the mouse cursor to jerk and that makes precision movement difficult. Weight: The weight of the mouse is lighter than the Huge, but heavier than the EX-G, and nearly twice the weight of the Logitech M570. Ironically, with not much pressure, it will slide across my desk, where the M570 under the same pressue won't move at all. The M570 is actually the most solid mouse I have. Quality: Just like the Huge, the buttons are a nice solid click, the scroll wheel has very obvious detents. The rose gold metal coloring on the scroll wheel adds an element of heft and quality. The side scroll feels well-made and like it will last, but I can't say for sure since I likely won't be keeping this one. The first one I had, there was a kind of grinding noise when I spun the ball in a particular direction. You know the sound, the sound of a ball bearing that is a little undersized for the space that it's in, so it bounces around. Well, the replacement has the same issue and it's just loud and annoying enough to bother me. Software: Just like the Huge, I had no trouble finding the driver/mouse assistant software. It took some getting used to how the profiles worked, but I did figure it out and the features are nice. Impressions: Overall, I like this one more than the Huge. The buttons are very well placed, though I miss the DPI switch on the side. Here it is on the bottom. Just as with the Huge, I don't like the stickiness of the trackball. Compared to the Logitech M570 and Ergo, which are smooth as butter, it's hard to justify keeping anything that doesn't move as smoothly, even if the buttons and scroll wheel do feel superior to those on the Logitech mice. Make: Elecom Model: Huge Type: Index-operated trackball mouse Ergonomics: Generally flat, soft padding on top of mouse. Mouse is long so that wrist also rests on it. Buttons large and easy to reach. DPI switch on side is quite convenient. Trackball is large and easy to get multiple fingers on. Movement: Trackball is heavy and sticks to bearings making movement jerky. Even at low DPI precision is decreased. Weight: Mouse itself is moderately heavy with 4 sticky pads on the bottom to prevent sliding. It does a pretty decent job of staying in place. Quality: Buttons feal nice, solid audible clicks. The scroll wheel also feels substantial and has solid clicks. The stickiness of the ball is a problem. The mouse does not sit flat on a flat surface, rocking forward and back on the two side pads on the underside. Software: I had no trouble finding the drivers/mouse assistant software. The software itself wasn't entirely clear how to use, but part of that was an issue with a game that didn't like the mappings. Otherwise, it was pretty easy to set up custom profiles. Impressions: Overall, it's not a bad mouse. I felt the size to be a bit too big. The biggest issue, and the reason I sent it back, was the stickiness of the trackball movement. There was nothing I could do to get it to roll smoothly from a stopped state, it would always jerk, making precise movements impossible. Not only was this not good for gaming, but even something as simple as copy and paste were difficult to use with this mouse.

**UPDATE** I originally bought this in 2018. I just ordered another. After nearly 5 years it is slowly dying lol. First a few weeks ago the up tilt switch on the scroll wheel completely stopped working. Now the down tilt even though I unbound it is causing movement issues, and Elecom software no longer emits(for lack of a better word) the correct key binds for other buttons(only non standard mouse buttons). I still have use of the 2 buttons above the scroll wheel, but they are only recognized as mouse button, not a key. Far right pinky button, Fn1, Fn2 no longer are recognized. This is still hands down the best trackball you can buy, since Microsoft trackball explorer from eons ago. This mouse is so easy to use for anything, and unlike the a smaller version of this, that I first bought, just killed my little finger as the right mouse button is angled so the edge is what your pushing, not on a flat surface. This is the perfect size, easy to use index and middle finger on the ball at the same time. Comfortable wrist pad which has held up perfectly as it is soft rubber. And of course the reason so many of us switch to these types of mouse, NO Carpel Tunnel pain or arm fatigue from moving a stupid regular mouse. Good Job Elecom. I love it's size it's close to the MS trackball explorer. Love the wrist rest. The downside is and I had to figure this out on my own. If you plan to use this for gaming you will only get to use 5 of the 8 buttons that it has. And to do that you have to NOT download the elecom assistant. If you use the driver and elecom assistant your games will not recognize buttons 4 and 5 and your now down to 3. Once I deleted the the elecom driver and assistant, games would now recognize buttons 4 and 5. The function keys are not mouse buttons and thus not recognized by any game. Least I haven't figured out a workaround yet. As for the mouse, if you have carpal tunnel or don't want it, a trackball mouse is the way to go. I have been using them for years and once you get used to them the non movement of the mouse just 2 fingers will not cause that carpal tunnel to appear even with long play times.

Update: 4-18-21 So I finally figured out why no matter what ball bearings you put in this mouse, it will never fix the drag issue from this mouse. It does not matter if you use the "ruby" bearings or "after market" bearings. The issue is not the type of bearings, it's the size of the bearings. And the second reason you will never fix the drag issue on this mouse is because of the type of ball they used. It has a very sticky surface. I'm not sure what type of coating they put on this mouse, but it has a very weird sticky feel. It almost feels like rubber. Between the larger bearings = more surface contact, and the strange coating they put on the ball, it simply ruins this mouse. I finally sent it back and purchased the Kensington Slim Blade Trackball. It has a bigger heavier ball, but it has smaller bearings. The ball is smooth, and rolls like butter with no hesitation from stop to go. Personally, if I could make the perfect mouse, I would use the Kensington ball and bearing set up with the button set up from Elecom and a better palm support. Now that would be a freaking awesome mouse. To be honest, I really miss the Elecom button layout. The Slim Blade doesn't even come close to the switch placement or switch quality. I'm not sure why after all these years, These companies cannot figure out that if they just listened to their customers, they could make a boat load of money if they would just make a good trackball. I would pay double for a mouse with that kind of build and quality. But sadly, I will put up with the button layout on the Slim Blade as the ball movement is perfect, even though the button layout is lacking. Please don't make my mistake and think you can fix this issue. I tried 3 different bearing sets and still could not get it to stop sticking. The palm rest issue could be dealt with as I talk about below. The Silicone spray was a stop gap measure and would only last about a week. Also, Elecom's customer support is ZILCH, NADDA, NEVER. They don't respond to any issues. And for that reason, I will never buy another Elecom Mouse period. So if you want to read my first updated review, be my guest. There are three major issues with this mouse. And I have tried to contact Elecom but it's been two months now and it's been crickets. So what are these three issues? Keep reading. Issue #1 You probably already know about the issue with the ruby red bearings right? I did, and purchased my first new set right out of the box so they would be here when I got the mouse. But the white bearings were super tight. So I purchased the silver grey ones thinking they would be better. But sadly, I would still get "first start" drag issues. I would clean the ball with just plain water and it would get worse for around a day before it would start to loosen up. Very frustrating. I tried warm soap and water and that made it even worse. This was the third separate set of bearings doing this and I was starting to lose hope. But after some serious brain storming I remembered I had a can of WD Silicone Spray. At this point I figured, what can I possibly loose? So I took the ball out and sprayed the end of a Qtip, and thoroughly rubbed each bearing and let it dry. This would fix the issue for about a week and then I would have to do it all over again. As it turns out as stated in my update, the bearings are too big and the ball is too sticky. It is a match made down below. And sadly, there isn't another ball anywhere that you can replace it with. Elecom in their infinite wisdom, used a very odd size for their ball and nobody makes one to replace it with. Issue # 2 So the next issue I started having was a stinging pain in my pinky. Never had this before, and for two days I could not figure out what was going on till I noticed that my hand was not setting on the mouse properly. Why? Because the mouse is not designed to hold your palm at the same level as the ball (see pics), and without even noticing I found that my pinky was trying to support my whole hand. I almost thought this was the end here. I even started looking for other trackballs to replace it with but finding very little. But then I had an idea. Is there something I could use or make, that would give me the support I need. That got me digging around on Amazon till I found the almost perfect solution. And if your looking for and easy fix, this isn't it (it's not hard either). But it did sort of fix Issue # 2 and Issue # 3 at the same time. And it's called Dualplex Neoprene Sponge Foam Rubber Roll Adhesive, 15 X 60 Inches X 1/16" Thick. The issue I had with the Neoprene foam is that it would wear too fast. I would get stress cracks where my hand rested on the mouse. To make it work, I needed some sort of coating on the foam to keep it from wearing out. So what is issue # 3? Glad you asked. Sadly Elecom used a foam pad with some sort of very thin coating on top. And this black coating, after only 4 months was starting to break down. I could see the writing on the wall, and knew that this was going to be a deal breaker for me, as I have read other reviews talking about this and had privately hoped that it was because of a PH balance issue with those buyers. Sadly, that is not true. So I took the Neoprene and built a gradual support pad for my palm and then covered the whole pad with a full Neoprene cover to seal it up. It almost worked flawlessly. This is almost the perfect stuff for this. It's easy to work with and very flexible. The adhesive works perfect for this. It will allow you to stretch a bit and fix while working with it. And then when you have it right, just keep pressure on all the folds for around 1/2 hour and it never moved or pulled and it's been over two days now and it still looks perfect. In fact, it's actually more comfortable now as it keeps my hand from sliding around on the pad like before. But as stated above, needs some sort of coating to make it last. As you can see in the pictures. There was a space of almost 1/2" between the mouse and my palm at a resting angle. This gap was what my pinky was trying to support without me even realizing it. By filling the gap, I not only fixed the pain in my pinky, but fixed the issue with the coating breaking down and ruining this otherwise awesome mouse. Well, sort of. Sadly, I doubt Elecom will ever take the time to read this review, but if it saves one person from making the same costly mistakes I made, it was worth writing this review.

Very happy with this purchase the Elecom Huge is definitely huge, but I have bigger hands so it feels quite nice. All the buttons fall nicely under my fingers and are easily in reach, with the exception of the scroll wheel which I think is a little far back for my thumb, but I have found a way to use the ball for scroll anyway. I did change out the bearings from the stock artificial ruby ones to G5 rated Zirconium Dioxide ones and it makes all the difference, the stock ones are a little scratchy, but also the trackball itself likes to be worn in too. I think its a finish or substance on that ball that takes some use, after a few days of frequent use the smoothness just got even better. I am not using the Elecom configuration software at all, I'm using HID-remapper by jfedor2 on github. Basically it's a Raspberry Pi Pico board that sits inline between any HID device and a computer and remaps any input. It's much much more powerful than what most configuration utilities can do, it supports macros and layers and is configurable with WebHID. All the buttons on this revision of the Huge are now standard inputs, so can be interpreted and intercepted much easier, unlike previous revisions. I've remapped left click to Fn1 and I have another button that toggles the ball to be the scroll wheel, super useful. All the internal switches are common and easily sourced and replaceable, it does come with Chinese Omrons for primary buttons, and the others are commonly found square micro switches. So should the stock ones fail, I know I can replace them all.

Commandée en remplacement de ma trackball Microsoft Explorer, cette trackball s’avère excellente. Très bonne expérience générale à l’utilisation. Seul défaut la molette qui ne tourne pas impeccablement mais bloque légèrement à la fin d’un tour complet! À voire dans le temps si cela va s’aggraver… En résumé très bon choix mais je ne crois pas qu’elle m’apportera la même satisfaction que la reine des trackball qu’elle remplace. 15 ans de bon et loyaux services qui seront difficile à égaler.

Tasarımını beğenip almıştım. Beklediğim kadar rahat, hassas, konforlu ve kullanışlı bir ürün değil. Kötü de değil tabii. İdare eder.

結構、大きいです。 その分、安定していて使いやすいです。 これまで、MicrosoftのTrackball Explorerを18年使用してきました。 その間、Logicoolも使用しました。 Logicoolの方がボールの動きも軽く、使いやすかったのですが、長く使用していると表面がベトベトしてきたので捨てました。 しかたなくMicrosoft Trackball Explorerを使用していました。 こちらはボールの動きが少し重いのが気になりましたが、耐久性は抜群でした。 さすがに支点のすり減りが限界に近いため、今回この商品を購入しました。 ちなみに有線タイプにしています。 購入前にはちょっと大きすぎるかな？と思ったのですが、机の上はそれ程狭い訳でもないですし、マウスの様に動かすものではないので、大きさは気になりません。 それどころか、この大きさのお陰で手を乗せる安定性も抜群ですし、手を置く部分が柔らかいので快適です。 この柔らかい部分の耐久性がやや心配ですが、1ヶ月使用した感じでは全くヘタリもないです。まだ、これからですけどね。 それでも操作中に少し動くこともあるので、もうちょっと重量があるか滑り止めを工夫すると尚良いです。 肝心のボールはこれまで使用したどのトラックボールよりも大きいのですが、動きはどのトラックボールよりも軽いです。非常に快適です。 軽すぎてマウスポインタが行き過ぎてしまう感もなきにしもあらず･･･。まぁ、慣れでしょう。 難点を挙げるとすれば、親指操作の左クリックの上にあるブラウザ「進む」「戻る」ボタンが親指操作ではちょっと押し難いです。特に手前のボタンは親指では押し難いですね。これは薬指ボタンに割り当てると良いかもしれませんが、私は会社のセキュリティ上、アプリは入れられないので変更不可で、これはあきらめてます。 とは言え、非常に満足しています。やはりトラックボールは大きい方が使いやすいです。 買って正解でした。これは良いものですね。

Bei mir rollte die Kugel auf Anhieb perfekt und wesentlich flüssiger und geschmeidiger als bei meinem vorherigen Logitech TrackMan Marble! Allerdings nicht lange, denn nach ungefähr einem Tag Benutzung wurde die Kugel zunehmend schwergängiger und wies zuletzt ein unangenehmes Losbrechmoment bei kurzen Korrekturen auf - Hautfett? Nach einer Reinigung mit Wasser und Seife war sie dann sogar noch schwergängiger! Auch eine Reinigung mit Alkohol brachte nichts - ebenso ein leichter Überzug von Silikonöl, was den Effekt der ruckeligen "Anfahrt" zurückbrachte. Die Lösung war dann tatsächlich, den Trackball erneut mit Alkohol zu reinigen, mit Graphit einzureiben und vorsichtig abzuwischen. Ich wollte allerdings erst Talkum probieren, hab den aber im Saustall der Werkstatt nicht gefunden - dafür fiel mir das Graphit in die Hand! Damit läuft er jetzt wieder wie anfangs, aber die dunklen Finger sind dauerhaft auch keine Lösung... Ich würde mir so sehr wieder einen Trackball mit drei Kugellagern zurückwünschen, wie meinen ersten Marconi von 1987! Der lief auch noch butterweich, wenn die Kugel bereits dreckverklumpt war! Und man konnte ihn in eine Richtung anstoßen - dann lief er dahin und konnte mit einem kurzen Tip genau an der gewünschten Stelle gestoppt werden. War ja ursprünglich ein kanadisches Militärteil für Radarstationen von 1952 (also NOCH älter als ich)... Das Teil wirklich für sehr große Hände gedacht. Die Verwendung eines Mauspads dahinter zur Handgelenksauflage ist wegen der Größe leider nicht mehr möglich und das zwar gelgefüllte Pad des Trackballs ist doch erheblich härter als so ein glattes Gelpad. Immerhin ist es mit einem fein genarbten Kunstleder bezogen, denn die Stoffpads, welche oft auch angeboten werden, scheuern über kurz oder lang, wenn man den Trackball so intensiv nutzt, wie ich. Probleme habe ich mit der schmalen rechten Maustaste, welche direkt rechts neben der Kugel liegt und der andererseits weit links unter dem Drehrad liegenden linken Maustaste, welche vorne ganz leichtgängig auslöst, aber nach hinten hin immer schwergängiger wird. Eigentlich haben beide aber einen erheblich höheren Druckwiderstand als beim TrackMan. Dies alles dürften jedoch Gewöhnungsprobleme sein - im großen und ganzen fühle ich mich mit dem Trackball auf Anhieb wohler, als mit allen anderen Alternativen, welche ich bisher probiert habe. Update: Nach ein paar Tagen habe ich mich nun an so ziemlich alle Funtionen gewöhnt, bis auf die doch recht schmale rechte Maustaste, bei der ich mich oft nicht entscheiden kann, ob ich sie mit Ringfinger oder Mittelfinger bedienen soll - die Kugel ist so groß, daß ich sie oft mit Zeigefinger und Mittelfinger gleichzeitig "bespiele" und um die rechte Taste zu treffen, nehme ich dann den Mittelfinger zu ihr runter. Es wäre besser, den Ringfinger zu verwenden, aber mit dem lande ich immer wieder auf der direkt daneben liegenden Fn3-Taste. Hier wäre eine einzelne, breitere Taste eindeutig besser! Mit der linken Taste komme ich mittlerweile gut klar und gewöhne mich sogar zunehmend an das Scrollrad Die Kugel läuft nun wieder dauerhaft seidenweich, nachdem ich sie mehrmals mit Graphit nachpoliert habe. Auch den Talkum hatte ich mittlerweile gefunden, aber bei dem ist der "Sanftanlauf" nicht ganz so gut, wie beim Graphit. Die anfänglichen Beschwerden am Handgelenk bei der Auflage sind verschwunden, nachdem ich das gesamte Gerät etwas zum Körper hin ausgerichtet schräg gestellt habe und den Stuhl ein klein wenig höhergestellt - schon passte es perfekt. Mittlerweile habe ich auch Grafikaufgaben damit bewältigt, welche mindestens genauso gut gelangen, wie vorher mit dem TrackMan und kann sagen, daß ich nun völlig zufrieden mit dem Gerät bin! Deshalb erhöhe ich die Sternezahl nun auf fünf! Update 2: Ein weiteres Problem mit Hautfett tritt von Zeit zu Zeit auf, denn der gezahnte Gummiring am Scrollrad dehnt sich bei Kontakt mit gewissen (leider bisher nicht nachgewiesenen) Bestandteilen auf der Haut extrem aus, sodaß er einen um fast 5 Millimeter größeren Umfang erreichen kann. Entsprechend "staut" sich das nun lose und nicht mehr in der Nut liegende Band beim Drehen des Scrollrades vor der Antriebsachse und bremst den Vorschub böse aus! Dies vergeht aber nach einigen Tagen wieder. Trotzdem ist es ärgerlich und behindert das flüssige Arbeiten mit dem Gerät enorm, wenn es denn auftritt! Hier wäre ein unempfindlicherer Kunststoffring anstelle des Gummibandes hilfreich. Diese starke Quellung von Latex habe ich auch schon andererwärts feststellen können - Lösemittel, Hautcremes und vor allem Bienenwachs lösen es in diesem Fall aus.
