Mad Catz R.A.T. 9 Professional Wireless Gaming Mouse

Pros: adjustable sides.
can adjust weight.
basically everything is adjustable which is nice.
scroll wheel is top notch quality.

Cons: the sensor is **** poor.
the feel isn't ergonomic whatsoever.
software is garbage at best.
no support from company.

Summary: the mouse is a good idea, and the adjustable parts are cool. But the 1 issue EVERYONE i have ever seen with these mice (rat9, rat7, ect) is the sensor fails and is a very poor quality for a gaming mouse. and when you are playing a fps and you are forced to fight with a mouse for control over what you are doing....lets just say you just use another mouse. I made this account to warm people that yes this is a good mouse but for REAL computer gaming DO NOT choose this product.
