nally people buy it for the rubber and its able to switch its dpi and the dpi .My friend used my mouse and its like 1800dpi that time he say i dont know how to control ur mouse can make the speed lower. so the good point in razer mouse is the dpi, grip and its able to switch its dpi or lower/ higher it but for higher dpi i dont think we need to use something like 4000dpi. I prefer copperhead will do
