ELECOM DEFT Trackball Mouse, Index Finger, 2.4GHz Wireless

Excellent office trackball. - It's easy to use - It has plenty of buttons for customisation and software to remap them - Small enough to not get in the way but still comfortable - Accurate with very little lift-off (better than the huge trackball in this aspect) - Very useful scroll wheel. Trackballs without a scroll wheel are annoying. - Lightweight and easy to carry - Wireless, so no cables to deal with. - Sufficiently sturdy plastics and no sticky rubber. - Good price for a trackball. The only downsides are - The back and forward buttons don't work on a Mac - The polling rate isn't high enough for gaming (you get aliasing problems).

First of all I'm writing this about the DEFT version of this trackball with the smallest of the 3 balls (M-DT2DRBK). I'm a time user of trackballs including the classic but sadly departed Microsoft Trackball Explorer 1.0 (I own 3), and the Logitech Trackman Marble FX (even rarer and more worshipped than the MTE). Is this an MTE replacement? Maybe. Overall build quality seems much better than the MTE. I've seen teardowns of the HUGE model, and if this model is similar, then build quality surpasses the MTE especially on the inside! Ergonomics wise.... the DEFT I find is not quite as comfortable as the MTE. The ball size (34mm) is noticeably smaller than the MTE (44mm). But for me at least the hand fit is very similar. This results in skittery accuracy for me. In terms of smoothness, those ruby bearings are just as good as the ceramic bearings I've fitted in my MTEs. (No nose grease was needed to get the ball spinning smoothly) Buttons feel is OK, perhaps a bit heavy. I'd prefer 2 buttons on the right like the MTE for backward & forward. Like others have said the 3 function buttons on the top are hard to get to, so use them for rarely used functions. I did try the HUGE size too. This too is built very well, but I found that for my hand size (22cm spread tip to tip from thumb to little finger) it was simply too big & so quickly became uncomfortable. The big ball (54mm) was nice though. Ideally I think I'd prefer the size of the Pro (44mm)...but as I write this, it's more than 3x the cost!!!!! The moral of the story is...if they fit your hand size the Elecom Trackballs are very good. If one size is wrong for you, do try another. I'll probably keep this one as a nice wireless ball, but so long as I can keep gluing them together again, it probably won't replace my MTEs full time.....

AN ELEGANT, UNDERSTATED JAPANESE WARRIOR! DESIGN AND FUNCTIONALITY. • This trackball is absolutely excellent. • It is well built, although it is made out of plastic, the trackball feels robust and compact, offering a plenty of sensibility and feedback when navigating the internet of working on applications. • The design is perfect, its looks is the perfect blend between high tech and professional devise; it has an underlying sense of Japanese wisdom and efficiency. • Its matt black colour, is understated, never looks dirty nor attracts dust • It is very intuitive, all its buttons are well located and fitted. They need to be pressed hard in order to operate then, which means they are long lasting. • The track ball has the perfect size (although it looks small at first). I soon realised the ball has the perfect size as it fits perfectly well with the buttons located in its left and right hand side. Three fingers can work in complete harmony. • Functionality!!!! Every button is programmable, with at 46 different functions plus gestures; this is what makes this devise so special. • The wheel’s performance is like a plane control, smooth and precise. • Improvements: It needs a protecting bag/box to protects its buttons The back of the trackball needs more high in order to allowed the hand to be fully supported on the devise.

The most important part of a trackball is how smooth it is and this just isn’t, there’s lots and lots of stickion, the ball just can’t make very fine movements at all. Aside from that pretty big issue it’s good, very comfortable for my small hands and doesn’t feel overly cheap and nasty. The switches aren’t anything special mind, just standard switches you’d get in a basic office mouse but they’re not bad and work well. I will say the right click button is quite narrow, I don’t mind it but some might. Overall nice and comfortable but not very smooth a ball at all

After suffering a scaphoid injury 10 years ago I have recurring wrist pain around my thumb area which can get worse or better depending on how I take care of my wrist. I work on a PC for 8 hours a day, and was starting to feel the pain ramping up. I could feel the movement of a normal mouse wasn't helping the issue so started reading into alternatives. A lot of trackball mice these days use the thumb for the trackball, which wasn't an option for me and I eventually settled on this one. It took quite a lot of getting used to to be able to use this accurately and efficiently, I have had this mouse for just short of a year now and using it is second nature. At first the ball doesn't really roll smoothly in it's cup, that improves with time. DO NOT use alcohol or any solvent to clean the ball/cup, the oil from your skin actually helps the ball roll smoothly so don't remove this if it can be helped, just wipe any dust away with a cloth. I feel I've had it long enough to confidently comment on it, the quality is brilliant, this thing feels like it'll still be going strong in 10 years easily. There is some Elecom software you can use with this mouse that lets you customise it to the nth degree. I have my 3 custom buttons at the top as cut, copy and paste, my left thumb buttons are forward and back. There are endless options for customising this and the software is great once you get it into English mode as it starts in Japanese. It seems to go through batteries quite quickly (needs changing every month) but I do have to have it on the higher power mode because of the distance from my PC. It only takes 1x AA battery though so it's no hardship. My one gripe and this is only really a personal problem (hence no star reduction) is that I would've preferred a trackball with the scroll wheel around the trackball as it is on some other mice. Having it thumb operated can sometimes cause me some pain, but I'll generally avoid scrolling this way if it's anything over a couple of pages.

I bought this mouse after struggling with wrist pain from using a traditional mouse for long periods. I’d also tried a thumb-controlled trackball, but that caused pain in my thumb. This one, which uses your index finger to control the ball, has been a total game-changer. It connects via USB receiver only (no Bluetooth), but setup was quick and completely hassle-free. The trackball is smooth, responsive, and needs just a light touch to scroll and move. I’ve used it for hours at a time, both for work and long Sims sessions, and it’s been completely pain-free. No wrist aches, no finger strain. Just smooth, comfortable use. I’ve got medium-sized hands and find the size perfect, I can easily reach all the buttons. It’s ergonomic, solidly built, and really easy to get used to. There’s even a handy little slot underneath to store the USB receiver, which is great if you’re carrying it around. Overall, if you’re looking for a more ergonomic mouse and thumb trackballs didn’t work for you, this one is absolutely worth trying. It’s comfortable, works brilliantly, and has made a big difference for me.

I have been advised to buy one of these for a while now. When I first started using it, it was a bit tricky to use, after using a mouse for many years. It didn't take long to get the hang of it. Now I prefer using it over the mouse. I had to change the settings so that the pointer didn't go flying around the screen. I was finding it really difficult to highlight text at first, but once I adjusted the speed of the pointer everything worked great, well, almost. The wheel on the side is a bit awkward to use for scrolling left and right, but having the aditional buttons to programme has helped to solve that issue. The back button is slightly too far back, but other than that, it is a great trackball and I would recommend it to others.

I had a centre trackball mouse for years before, and couldn't belive how little there are on the market these days, this is a great mouse, and play sized, where others I've read reviews on are quite larger. It still has scroll, left and right click as well as customisable buttons, so all good

Mouse veramente interessante e comodo da usare

I like DEFT over my old Logi marble trackball. Their footprints are pretty much the same. +1 Lots more button with scroll wheel. +1 The software works fine with translator from my phone. As I just need to configure it once. It's alright. +1 I had lag initially. Turning power slide to low power resolved most of the problem. +1 The ball is lighter. Dry skin does reduce grip. Lotion does help in my case. :0

使用していたもののボタンがおかしくなってきたので在庫があるこちらでリピート注文。 流石に使用感は変わらず。使い勝手も良し。 次は在庫が無いだろうから似たような商品がある事を祈ります。

You don't need to move,it's made for small hands -1

All in all a great product. Size, feel, quality all on par or better when you consider price. I bought this one just to try it out and see if the company was legit. I can honestly say that i am more than sold on the company and the quality and i have no reservations about spending considerably more for one of their high end models. Im actually excited to see this company's high end features bells and whistles.. The only real issue with it is customizing the extra buttons. The software they provide is garbage. And to make matters worse, isnt even in English. You will have to find another software to customize the 6 7 8 buttons. This is the issue that keeps me from giving it 5 stars. But other than that, its terrific. Fast, accurate, comfortable. And at fair prices... i highly recommend. UPDATE: Its now 2023. Ill save u the details but I was asked to give my opinion on ergonomics as it relates to office workstations. I was given the opportunity to do some research on several companies including Logitech, Kensington, and Elecom. The funny part is no one on the team had even heard of Elecom before my recommendation. Comes to find out, they chose Elecom mice for every new workstation in the facility including the main dispatch center hub where they no doubt are going through a trial by fire. And not a single complaint has come up about the performance, and they were actually praised for their customization as dispatchers like to program their mice with their own shortcuts for maximum speed and efficiency during their shifts. So I must retract my initial review about their programming software and tell you that it's much improved. And that's not just from me. That's from a whole 911 dispatch center crew of over 30 dispatchers who have no skin in this race. I'll be honest I forgot about this initial review and never would have paid any attention to it if I had not given it a poor review initially. I stand corrected and concede that improvements are the new order of the day. So Elecom gets the 5th star. Oh, there is still 1 tiny issue... The product info is still written in Japanese so you have to go to the Elecom website to get it translated to English. Lol. Pound for pound.... And I can't believe I'm saying this... Better than Logitech and Kensington. Elecom quality and price is equal, if not better than the big guys , and they offer more innovative options to their products so u get more for your money. At the end of the day, Elecom is doing what any new guy should be doing., better product at better prices, and letting their performance do the talking. And again, Elecom doesn't even know I exist and they don't pay me a single dime to say any of this.... I just believe good quality products should get a little recognition every now and then .
