The Mad Catz Cyborg R.A.T 7 is a unique and innovative option for the pc gamer. The sensor issue is a serious flaw and could make a completive gamer overlook the R.A.T 7, feeling it’s not worth the risk. I am also disappointed in the finish breakdown however small the imperfection. The flaws are outweighed by the customization in this case though. The ability to change and tweak almost all the physical aspects of your mouse is an experience not available elsewhere. The Mad Catz Cyborg R.A.T 7 is still the most innovative gaming mouse on the market. A full two years after its release it is one of the top mice in its price range. If you are looking for something truly different, then give a R.A.T 7 a try. You will be glad you did!
