Review on Perixx PERIMICE-804 Bluetooth Vertical Mouse - Wireless Connection For Windows & Android, No USB Receiver Needed by Matthew Nunez

I have used vertical - upright - ergonomic mice for several years now. My boss even teases me about my 'space age' mouse I use at work. I have used many and currently own a wowpen penjoy v1, Anker TM137u, etekcity "scroll endurance", memteq (wowpen knockoff), and several others I have put through the paces and worn out and bought again.This mouse came into my radar as a new brand and slightly different design, so I thought I would try it out, especially at the price point it is offered.Pros:-Inexpensive-Plug and play worked fine and quickly-Good placement of the thumb back and forward buttons-Grippy texture on the thumb rest area-Vertical angle seems on par with most vertical mice, not too horizontal, but not completely upright.Cons:-Small to hold, insecure while moving and clicking, even for my smallish hands-Had a few times where it seems either this mouse or my laptop didn't like the device and forgot it was attached. Unplug and replug in usb and it was fine. scrollpad on laptop still worked in the meantime. This may have been a fluke, but nothing changed on the laptop during this time.-Seems a bit under designed for actual comfort while using. My index and middle finger wanted to curve more to maintain neutral posture, but the mouse doesn't curve there.Conclusion:As an upright mouse, it is a little small, even for my hands that aren't that big. The front buttons could be curved a bit more, so it would be easier to hold comfortably. I like the placement of the thumb back and forward buttons, and the grippy thumb hold area (without that it would be near impossible to hold securely while moving and clicking).
