Mad Catz R.A.T. mice have a long history with PC gamers. If you?ve used a R.A.T. mouse you know it is unlike anything else out there, yet many people overlook these mice and I?m not sure why. Some people have told me they don't choose these mice because they don't look like they would be comfortable, yet they have never used them. Every R.A.T. mouse that I?ve used not only has been comfortable, but extremely functional. Mad Catz recently released two new R.A.T. mice, the PRO X and the PRO S. Today we will be taking a look at the PRO S which features a PixArt PMW3310 5000 DPI optical sensor, 8 programmable buttons, and an adjustable palm rest. The PRO S is designed to be a tournament mouse to it is also very lightweight. Let's get to gaming and see what the PRO S is all about!
