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.

The ProtoArc EM11 vertical ergonomic mouse has been a fantastic upgrade for my workspace. I spend long hours at the computer, and this mouse has made a noticeable difference in reducing wrist strain. The vertical design feels natural from the moment you start using it, and within a day or two, it becomes second nature. The Bluetooth connection is reliable and quick with no lag, and I love that I can switch between devices effortlessly. The mouse glides smoothly, tracks accurately, and feels incredibly responsive whether I’m working, browsing, or doing basic editing. Battery life has been excellent as well. A single charge lasts much longer than I expected, and the rechargeable feature makes it even more convenient. The overall build quality feels solid, and the matte finish gives it a premium feel. If you’re looking to ease wrist discomfort or simply want a more ergonomic setup, this mouse is absolutely worth it. It’s comfortable, efficient, and a noticeable improvement over a standard mouse. Highly recommended! Read more

This is such a great mouse! I have been struggling with wrist pain for a while from using a mouse all day for work. I was recommended to get a vertical mouse by my doctor. He said they keep your wrist in a more natural position. I spent a while looking for one that I like, and I basically narrowed it down to either this or the Keychron M5. The only other ones that seemed appealing were the 2 Logitech models, but they were both far too expensive. I have also heard horror stories about their durability. Finally, I saw this model on sale for $19, so I pulled the trigger. I am very happy I did. Even after just a few days my wrist pain improved. The grip feels very natural. The way they describe it like a handshake is very accurate. I am happy that I don't have to deal with so much pain in my wrist anymore after a long day sitting at my PC. I think the multiple connection methods are nice too. I can keep the USB dongle plugged into my desktop workstation and switch to the Bluetooth whenever I need to use it with my laptop. I don't use it with my laptop that often, but I do have a Thunderbolt dock at my desk that I use occasionally. Switching input methods works well. I have not noticed any input latency or lagging. Nor have I had connection drop-outs. There are no drivers or software to install. That is greatly appreciated because I can't stand having peripherals that need to install special drivers and applications to configure the settings. This has none of that crap. You just connect it and you are good to go. I'm a Linux user as well, and I've had no issues. The DPI switch is nice to be able to change the sensitivity. I was worried the silent buttons would feel mushy, but they don't at all. Somehow they have a very tactile click without making any noise. The noise isn't an issue for me, but I can imagine anyone working around a bunch of other people would appreciate it. The scroll wheel feels really nice too. It has a nice soft-touch finish and smooth operation. The forward and back buttons feel nice, but they are not silent like the left and right click. It's not that big of a deal, but it would have been a nice touch. For those who are gamers, I don't think this would make a great gaming mouse. For that I will probably hang on to my ultra lightweight mouse that has a honeycomb shell for ventilation and weight reduction. This mouse is by no means the heaviest mouse I have used, but it is nowhere near as light as my gaming mouse. I cannot speak on the battery life since I have not had it that long, but I will say after a week I have not had to charge it. at all. I just pulled it out of the box and started using it. Perhaps if I have an issue with the battery life I will update this review in the future. You really cannot go wrong with this ergonomic mouse. Read more
