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

Mouse is ergonomic and vertical hand grip definitely eliminates palm pain. Rubberized parts of mice is nice and have nice feel. However, button are not sensitive enough so when you click the mouse botton, the mouse moves left. This is quite annoying and caused me to retire this mouse. I used it for couple months at work so I have over 300 hours of use on this mouse contrary to many users who posted their reviews after using it for 5 minutes. I will sell it for sure because this mouse is not a keeper. I replaced it with Logitech G600 and Roccat Kova+ and noway I am going back to this Perixx Perimice-515 mouse. It is unfortunate that rating of this mouse got skewed by reviews of people who got this mouse for free and used it for few minutes. Putting 2 stars to offset inflated ratings posted by reviewers who got the mouse for free and used it for few minutes.
