Most mice that I've purchased for my PC Gaming setup all functioned normally but as soon as I launched a game they would stop receiving any input. I eventually looked into it and I found that all the mice I used didn't have the primary format as "PC Gaming" like this mouse says in the details section. I went to my nearest JB and purchased it to find that I could now play games AND use my mouse at the same time! Not only did it work, but with its "Flux Interface" and "7200 DPI Optical Sensor" I found that my aim was so much more precise. This mouse is a must have for any aspiring PC Gamers out there.
