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, BlackClimatePartner certified

I didn't want to believe it, but...I bought it on sale, and WOW! Yup, a mouse did that.The initial quality and boxing are as good as you will find from any manufacturer. I do wish manufacturers would work towards the most sustainable packaging, but what is provided is very well done.Mouse:-- Soft touch outer "skin" that is very comfortable-- Dreamy, silent buttons and scroll wheel attenuated silently and with soft, accurate positioning-- Excellent 5-button + configuration and connection options making it a fantastic full-sized mobile ergonomic mouse.My hand measures 7.6" on A axis, and I feel the mouse is adequate, but understand I am at its limit. Still, it feels great and performs as expected, and reliably as expected. I have always taken a light touch to mice and this shape encourages that relaxation for my hand at finger length.As a vertical ergonomic mouse, I have used several from Logi, Anker, and others… this is by far and away the mouse that checks all the boxes, and for an incredibly reasonable price.Super-easy setup (either Bluetooth, or wireless adapter included), and the battery has outlasted expectations for its first charge so far, in writing this early review.Cheers - Nguyen should be proud of this. I'm an old-time user from the East Coast USA, and have mice that date over 30 years old, and no one has really ever put together a complete ergonomic mouse that works ubiquitously*. This is the winner.*I use "Mouse Fix" on macOS for button programming - but it runs natively on both macOS and Windows just fine.**I would also like to see a vertical measurement on vertical ergo-mice - wider hands need the height, but even at the limits of this mouse, I feel okay and relaxed on this mouse with my long-time HandStands bean-bag wrist-wrest.

I spend a lot of hours on the computer for work, and this mouse has made a huge difference in comfort. The ergonomic design feels very natural in the hand, reducing the strain I used to get in my wrist and fingers. The buttons are responsive, the scroll wheel is smooth, and the wireless connection is stable with no lag. Battery life is impressive—I can go weeks without recharging. It took a day or two to adjust to the shape, but now I can’t imagine going back to a regular mouse. A great choice if you want something comfortable, reliable, and well-built for everyday use.

Fantastic mouse/keyboard combo. The mouse took some getting used to, because of my larger size hand, but I adjusted by using my middle finger on the left click giving me a more natural feel. I hope they come out with a 2nd version for larger hands. The battery life and comfort are amazing. The mouse has really responsive DPI control, and the button layout is user friendly. All-in-all a very well designed, low profile ergonomic device.

I've heavily used computers for both work and gaming for decades. I don't generally get pain or soreness in my wrists, even with heavy use, but as my good friend 'time' has shown me, all good things must come to an end.These days, after extended use, I've noticed hands and wrist are getting tired, sore, and every now and then actual wrist pain, so I've finally taken steps to make my setup more comfortable and ergonomic.One of the things I've seen a good deal about lately were vertical mice - had never used one, but was curious to check one out. It make sense, right? That a better angle would be better for your wrist, so I went ahead and purchased this one.After using it for a few days, I am an absolute believer. It did take a day or so to get used to, but now that i'm used to the positioning, it feels so good. Wrist definitely feels more comfortable.With the actual mouse itself, it's pretty cheap, but works well.-Click response is nice. Nice feel to it-Have experienced zero connection problems, so far works great-Nice position for the charging port, no issues using it easily while plugged in-Weight is lightHonestly, aside from adding a few more buttons that you can program, and maybe higher DPI options, this is a great all around mouse that while it does take a little getting used to, once you do, it's a game changer.

Real customer: this mouse exceeds my expectations given the price (half of the logitech counterpart). It's very comfortable for relatively small hands, easy to connect via bluetooth (or USB) to my laptop, and the packaging/product seem really well made and of high quality. The mouse slide smoothly and has two buttons on the side for customizable functions. It has quite click - I don't need it at home but maybe useful in office environments.

I don't like this mouse. But I have small hands. This mouse is difficult to control. The clicks don't stick. I have to go back and re click things twice a lot of times. The curser jumps around the screen. It's not precise. Using this mouse actually slows me down. When I switch between this mouse and my old one at my other work station ( I go back and forth constantly throughout the day) the difference is clear and it confirms how much I hate this mouse. The quality is good, and it is actually ergonomic as in it doesn't cause any pain after a long day of working. But the ease of use is just not there for me. I used daily on my main work station for well over a month and never got used to it. So ordered another Logitech M705 even though it hurts my hand after a long day of use. At least the curser is easy to control and it doesn't slow me down.
