ProtoArc Ergonomic Mouse, EM11 NL Bluetooth Rechargeable Wireless Vertical Mouse, 3 Multi-Device Connectivity for Computer/PC/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, Black

This ergonomic mouse has been a game-changer for my work setup. The build quality is excellent—it feels solid and well-made, with a comfortable, ergonomic design that fits perfectly in my hand. After using it for long workdays, I’ve noticed a huge difference in how my wrist feels—much less fatigue compared to a traditional mouse.The buttons have a satisfying, smooth click that adds to the overall premium feel. I also love the easy multi-device connectivity. Switching between my laptop and desktop is as simple as pressing a button. If you’re looking for a high-quality ergonomic mouse that combines comfort, functionality, and convenience, this is a fantastic choice.

On my initial usage, this vertical mouse impresses me. It is smooth and responsive to commands. It has a handsome fit and finish and feels good in my hand. Its scroll lock is superb, engaging on light finger pressure and moving the cursor quickly up and down the screen without hitches in its get along. The screen forward and backward keys above the thumb rest respond crisply, although I don't often use these tools. The product is attractively priced. It is too soon to know if the mouse it durable, but the manufacturer thinks it is. It offers a two-year warranty. My one criticism is that the dpi key behind the scroll wheel it too easily toggled. The fingers on the left and right curser keys tend to brush across it, sending the cursor on a wild ride into temporary oblivion.

Almost perfect. It’s a good price, the scroll wheel does not cause pain after long use, it’s good speed on the scrolling, with decent buttonsBe aware of: it’s really hard to tell when you’re almost out of battery, and battery life isn’t the best. Also, the DPI toggle is positioned in a way/functions in a way where it is accidentally triggered/clicked frequently

I wasn't sure about buying an unknown brand, but this mouse has surprised me in all possible ways:1) Ergonomics 10/10 - one of the best hand positions imo.2) Functionality is 10/10 - long battery life and no false tracking.3) Ease of use 9/10 - finding the best hand and wrist position to use this mouse might take a little time.4) Connectivity 10/10 - it connects through Bluetooth but comes with a dongle that can provide direct wireless connection.I use this daily for internet browsing, word processing, and CAD design. I am keeping it and will most likely try other products from the same brand.

I have nothing but positive things to say about this mouse. Size is perfect. Weight is perfect. The silent clicks are also a little tactile, also very pleasing sound. I got this mouse about a week ago, never charged it, and it’s still got juice. Battery life is incredible. Zero connectivity issues even when switching between devices. The material it is made out of is awesome, very solid PBT feeling buttons, and there is like a super soft silicone on the body. 100% recommend.

I developed painful RSI in the early 1990's over the course of my career in Computer Technology. My arms, wrist and hands hurt! I almost had to learn and start a new career where computer use would be minimal.Through the years, I have had many ergonomic mice-some effective, others, not so much. I'm retired now but my computer use is still heavy.Came upon this, the ProtoArc Ergonomic Mouse, EM11 NL Wireless Vertical Mouse, and I am very happy with it! I can spend all day computing and remain pain free. The learning curve was pretty short. I like that it is bluetooth, rechargable and the battery lasts a long time. Also can connect through UPC port. I can use it on different surfaces. It seems to be well made as I have dropped mine on the floor and it's fine and working. Looking at reviews, only 3% gave it one star, so most people favor it. I recommend this to all who are suffering with RSI

I mainly use my computer for school (email, internet, Word/PowerPoint, etc) and this mouse is great for it. I have used a Logitech roller/ball style mouse (photo) for the last decade or so, but I wanted a change and I like this much more.I wear L/XL gloves and the mouse is a good size for me. Haven't noticed any issues with my pinkie or palm dragging, but I mainly just move my wrist and fingers.I was looking at other brands in the $80+ range and I'm glad I bought this one instead. On the other end of the spectrum, I have a cheaper mouse (photo) that is the same verticle/ergonomic style and I don't like it. So I would choose this mouse over the $9-$12 options on amazon.Pros: one of my favorite features is that it's rechargable and you can use it while charging (so if the mouse dies while you're working you don't have to wait for it to charge). I never turn it off and the battey lasts more than a week but I don't know the exact number of days. It's comfortable and responsive, Bluetooth stays connected. There is a button to cycle through 3 or 4 sensitivity (dpi) options. Has the option to use the included USB dongle instead of Bluetooth.Cons: don't really have any. I don't game or do any photo editing/art stuff, so I don't know how it would work for that.
