ProtoArc Ergonomic Vertical Mouse, EM11 NL Bluetooth Mouse Wireless, Ergo with 3 Multi-Device for PC/Notebook/Laptop, USB-C Rechargeable Mice for Windows, Mac OS

I loved it, it is so good, the shape is so good, if you are using this type of mouse first time, it will take some time to adjust, but after some time, it will feel so good and very easy to use. Battery life is also very good.

A really great purchase. Good for your arm.

Great product

THis product is OVER-Designed. The lower part of the mouse sticks to the palm which makes it hard to move it on the mouse pad. Useless and causes me little anxiety.

Wow, amazing product, perfect for hand, comfy, well designed and executed, and packed and delivered. Well done, i am impressed.

The mouse latency works better without lag. the difference is the unique design , when use it for the first time you may feel uncomfortable until few weeks.

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.

Cómodo, la pila dura mucho, definitivamente gastar un poco más vale la pena en comparación con otros similares un poco más baratos

I've had this for several months now, it's been very comfortable and it's almost shocking how little you need to charge this. I've charged it twice in almost 8 months! Once when I first got it, left it to charge for a few hours, then again after a few days because I wasn't sure how long it would last, and then never again. I'm in tech so I use my mouse for at least 6 hours a day on most days (when I'm not using the touchpad). The buttons are clicky but pretty silent, scroll wheel is nice, it has back/forward buttons which I always like, and a quick dpi switch button, it also supports 2 Bluetooth connections and a dongle! This is genuinely one of the best mice I've used. My only gripe is ironically the shape, it makes it a little awkward to throw into a bag to use on the go. I've had some issues where after taking it out of my bag, the plastic over the left/right click was a little out of place and I had to fiddle with the plastic to get it back into place, but I assume that's more of an issue with storage than it is the mouse.
