This wireless ergonomic peripheral adjusts perfectly to my hands and provides great comfort during long hours of intense gaming sessions. The illumination feature enhances my gaming experience and adds the right ambiance to my setup. As a result of using this product, i found that my hand fatigue reduced, and my overall gameplay improved .However the rechargeable battery life could be better; I need to charge it frequently during my weekend binge sessions. But overall, its a great addition to my gaming arsenal and has not disappointed me yet..
