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

This model is my very first vertical mouse. I tried it and it took me a couple of hours to get used to moving the mouse around. My old mouse was a 2008 Cooler Master mouse, and switching for this one was a big step back. I specifically wanted a wired mouse because I don't like my mouse movements to lag. I am not using this mouse for gaming, yet it is disapointing in general day-to-day use. I move the mouse and sometimes the cursor stays in place, which can be incredibly frustrating. I bought two of these, one for me (used in MacOS Yosemite) and one for my father (he is using it with Windows 8). Both mice possess the same problem, so it appears to be a brand or model specific issue. I was disapointed mostly because I now feel that the Perixx Perimice 515 is overpriced for what it offers.
