EM11 NL Wireless Ergonomic Vertical Mouse, Rechargeable, Black

I bought this mouse at the same time as an ergonomic mouse pad because I was having so much elbow and wrist discomfort while working that I was starting to wonder how I was going to get through my workday. I can't say which one deserves more of the credit since I started using them together, but WOW. Within a day, I noticed a huge difference in how my arm and wrist felt while working. This mouse is incredibly comfortable. The vertical design puts my hand and wrist in a much more natural position than my traditional mouse. The instructions say to allow one to two weeks to adjust to using a vertical mouse, but honestly, I was comfortable with it on the first day. My hands are about average size, and the mouse fits my hand perfectly. I also love that it can connect to three devices. I currently have mine connected to two different laptops, and pairing was almost instantaneous. There was really nothing to it. I was a little concerned about using Bluetooth because one of my laptops has a tendency to lose its connection with other Bluetooth devices, but I haven't had any connection issues with this mouse. The battery life has been impressive too. I've been using it for about a month, have only charged it once - when it first arrived, and it's still going. It's your typical black mouse, but it feels durable and well made. My one annoyance is the scroll wheel. I sometimes inadvertently press down on it while scrolling, which activates auto scroll. The auto scroll isn't particularly smooth either, so I'd rather not activate it at all. I'm getting better about not accidentally pressing the wheel, but it still happens occasionally. Paired with my ergonomic mouse pad, this has made working at my computer so much more comfortable. The comfort alone made the switch worthwhile for me, and the battery life, easy pairing, and ability to use it with multiple computers are bonuses I actually use.

Super easy & quick to install. I think from box to using it was less than 2 minutes. Maybe just 1 minute. It holds a charge for a long time. And, for clarity we use our computer maybe a few times a day or less and sometimes that is hours and other times less than a few minutes or maybe we don't use it for days. When we use the computer frequently, we do have to then charge it but no big deal because you plug it in to the front of the mouse and then into you r computers USB and you keep using it. The wire does not get in the way for us when using it while charging. It slides nice and easy on the desk and is very responsive. The action on the buttons is nice and different than a lot of computer mice I used in the past. Instead of a click this is more like a soft press click. I was surprised that I liked the way the buttons action work on a mouse, but this one is different for me. Overall, it sits comfortably in my hand, slides smooth and easy all the time and works flawlessly thus far. I definitely recommend it.

This contours to your hand and it’s very easy to use. It required no learning curve. It’s quiet, comfortable, it’s accurate with the clicks, there are no lags. It’s rechargeable, and Bluetooth enabled. So far I really enjoy this mouse.

I'm a long-time MX Master user who had their mouse buttons stop working and didn't want to spend another $100 on a new one. I found a handful of 'budget' clones and replacements, I tried a couple and returned them all. But this one...this one I think I'm keeping. It's one of the rare budget products that is compared favorably to big name, much more expensive products, and it actually--mostly--holds up. Obviously, the standout feature is the ergonomic vertical design. If you haven't used one before, like myself, it feels weird at first, but after an 8-hour work day the shape felt natural and I feel like it required less grip pressure than I'd have initially imagined. It's comfortable! This one is going to depend on hand size, though, I would imagine. I would say I have medium-ish hands, and for me it it works. My pinky does drag on the mousepad a bit but I can pull it up to avoid. I haven't had it long enough to comment on battery life yet, but a week in it has been great. The build quality feels better than some of the other budget mice I tried. Surprisingly premium considering the price. The main two mouse buttons are excellent, and very reminiscent of my MX's 'quiet clicky' buttons. I do have occasional times when I'm clicking and dragging, and it stops 'unclicks' even though I'm still holding the button down. The side buttons--the forward / backward--are not good and one area where it shows it 'budget' build. They feel cheap, they have a cheaper click and are louder. But, they're completely functional. The scroll wheel is also not a strong point, another 'budget' build point. It's adequate, but I find it too slow, has occasionally missed scroll inputs, and the click also feels cheap like the side buttons. Not bad, not great, just okay. Overall, I feel like I'm getting 80% of the experience of my premium MX mouse at 25% of the price. It's comfortable, mostly well-built, mostly reliable, and effective at reducing some wrist strain (in my case, anyway). The scroll wheel and side buttons keep it from attaining a "near-perfect" for me, and I'm sure the shape will not be for everyone, but I'm going to hang on to mine.

I absolutely love this mouse. The ergonomic design is incredibly comfortable and keeps my hand and wrist in a much more natural position, especially when I’m working at my computer for hours at a time. The buttons are easy to reach, it feels smooth and responsive, and the shape is comfortable without being bulky. It also looks sleek on my desk and feels much more premium than I expected. If you spend a lot of time on a computer and want something comfortable, functional, and easy to use, I highly recommend it. Definitely a 5-star purchase!

I saw this mouse reviewed on YouTube and figured that, for $26, it was worth a shot. I’ve tried just about every type of gaming and ergonomic mouse—from reasonably priced to “nearly a house payment.” I also work in IT, program, play games, and write video game mods, so I spend a lot of time at my computer. This mouse is impressive in every way. It feels surprisingly premium, with a soft-touch rubberized finish, while still being lightweight like a gaming mouse. I have small hands, and the buttons are perfectly placed. They have a nice tactile feel with just the right amount of feedback. The trackball is smooth and doesn’t feel like I’m rolling a soda can over broken glass—looking at you, Razer. For programs that require frequent middle-button clicks, the reduced strain has been a huge relief for my shoulder. As an ergonomic mouse, it’s incredible. I’ve tried several big-name brands, and they all came with the usual disclaimer: “It takes a few weeks to get used to.” Not this mouse. I set it up, turned it on, and started using it. It felt natural immediately—like a perfect extension of my hand. My wrist pain has gone away, and I can now work and enjoy my hobbies without constant discomfort. The sensor is extremely responsive with no noticeable lag. The wireless connection simply works: plug it in, connect, and use it. That should be normal, but somehow it feels like a minor miracle. I highly recommend the ProArc EM11NL. I’m planning to buy a few more this week. At this price, it’s practically suspicious.

I have bought this twice, three times if you count the Jelly Comb mouse I bought before, because ProtoArc bought Jelly Comb). I bought the Jelly Comb mouse for work in 2020, and when I couldn't find Jelly Comb anymore in 2025, I bought the ProtoArc mouse, possibly for my home (?) in 2025. A few weeks ago, the scroll wheel of the Jelly Comb mouse wheel I had at work went wonky. (After six years). So I went to Amazon, found the mouse I'd bought last year that fit my hand perfectly and was basically exactly the same as my 2020 Jelly Comb mouse and helped with my carpal tunnel, and ordered another one. Predictably, it worked perfectly. But I like having a spare mouse around because sometimes they go bad, so I opened up the old Jelly Comb mouse (had to find a video about how to open an ergonomic mouse, but I figured it out), cleaned the wheel with rubbing alcohol, and put some PTFE tape between the wheel and the rubber, and it's working perfectly again. So now I have three perfectly working mice - one for home, one for work, and one for... trips, I guess? Or as a backup? The Jelly Comb mouse was perfectly fine and I would've ordered it again if I could've found it. It's a great mouse that basically lasts forever, and the batteries last so long I forgot the old one even *had* a battery in it, but then ProtoArc went, "You know what? Making our customers buy batteries is silly; we should just include the batteries *and a USB C charging cable*; that'll be a nice extra touch," though they did that, too. Oh, and they also apparently thought, "Sure, we have a USB adapter *and* bluetooth, but what if people want to connect it to, like, two devices but they want to use Bluetooth for both? What if they have, idk, a desktop, a laptop, and a phone, and they want to use bluetooth to connect to their laptop and phone and can plug the USB dongle into their computer? Better throw in the ability to easily pair with TWO devices via bluetooth!" But that's not what inspired me to write this review. It's the packaging. ProtoArc clearly pays their designers very well. The box looks like something Apple would design. When I opened the box I kinda rolled my eyes and thought, "This is a cheap mouse that does not need packaging this pretty." I'm writing this review in 2026. By the time I need another mouse, I can't imagine how they'll have thought how to make this thing better because it was exactly what I wanted in a mouse before. They'll probably have figured out a way to make sure the mouse wheel doesn't get sticky and need taken apart and cleaned after 6 years. (GASP! Maybe they already did... I'll find out in like 6 years 😂 They did a great job. If I lost enough mice that I needed another one, or if enough of them broke that I needed to buy another, I would buy another one from them. I've also thought about buying one of their ergonomic keyboards, that's how much I like their mice. NOTE: ProtoArc did not pay me to say any of this, or offer me anything in exchange for writing this review, and this is not AI. I just really like this mouse.

Influencer got me on this one. Seems like a good idea, feels nice in-hand right out of the box. I could not get a comfortable grip or angle using this, it constantly feels like it slipping forward out of my hand. This mouse created fatigue and discomfort in the hand and forearm; inducing the problem it was intended to solve. Tried it on the desk pull-out keyboard tray, I tried it on the desk top, I tried adjusting my seat height, I tried using it with and without a mouse pad (wrist support & none), I added hocky tape to improve grip (helped a bit), I tried giving myself some time with it for each change. Nothing worked, went back to my old mouse and search for something that works for me. More than 30 days trying so I can't return it. Gave it to someone else, maybe it will work for them. Maybe a smaller hand will rest better on the curve. Cons: All clicks do not register the first time. Battery non-replacable. Two stars removed for reasons given. Pros: Good quality feel to the materials. Quiet clicks on LR buttons and audible clicks for other functions. Good button travel. Good feel on scroll wheel. Looks modern.

والله لا يعلى عليها ممتازة ومريحة بصراحة استهنت فيها قلت شكلها ضحكة بس جربتها للامانة ممتازة ومريحة واعصاب اليد ارتاحت عكس الفارة القديمة اللي تضغطها بالسبابة تسبب لك شد في اعصاب اليد تتعب شوي انا اقول للي يبي يشتري هذا النوع ياخذها ماراح يندم

after 9 months of using this mouse, it is absolutely 5. After you adapt to use it (use rough mouse pad) you can see how seamless it is especially when transferring signal from one device to another. Battery is also amazing and material and quality are superb. Above all of that, the vertical configuration helped in relaxing my hand and reducing the pain.

This ProtoArc ergonomic vertical mouse is such a good buy. It has two connectivity modes (USB-A and Bluetooth) which work great out of the box with no need for any software installations. With the Bluetooth connection, you can connect up to two devices. While you cannot use them simultaneously, you can easily switch between them with the click of a button. Other features include: 1. Power: It is powered through USB-C, and you will find yourself recharging only about every three to six months depending on your use. It charges quickly. 2. Navigation: It has two side buttons for moving forward or back on a webpage, although there is no built-in native app to edit these buttons. Overall, it is great for your hand and recommended for people with big hands.

Mouse de gran calidad en los materiales se siente como un mouse de arriba de $1,000. Los clicks casi no se sienten y ni se escuchan el confort en la mano es estupendo la verdad quede encantado con el

I absolutely love this mouse. I bought the ProtoArc ergonomic vertical mouse to help reduce wrist strain, and it has made a huge difference. It feels very natural to hold and keeps my hand in a much more comfortable position compared to a traditional mouse. The design is sleek, lightweight, and fits nicely in my hand. The buttons are responsive, the scroll wheel is smooth, and the wireless connection has been reliable with no lag or dropouts. It did take a day or two to get used to the vertical design, but once I adjusted, I found it far more comfortable for long hours of work. I use my computer for extended periods, and this mouse has significantly reduced the discomfort I was experiencing in my wrist and forearm. Highly recommend this mouse to anyone looking for a comfortable, ergonomic alternative to a standard mouse. Great value for money and one of the best office upgrades I’ve made.
