I have the Razer Goliathus Fragged Control Mouse gained me because my old was durchgeschubbert after many years of use. I have so far not heard anything bad about Razer and thought to myself that I really can not go wrong with it. This has proven to be richitg. I have a RAT7 and have to say that to "Control" really something to it. The surface looks high and is made of fine fibers click really precise, goals or whatever else make always possible. The fact that seams are at the edge, prevents the pad fray sometime. The underside is made of rubber, which makes slipping impossible. All in all I could not detect any negative points and the mouse pad'd definitely buy again.
