When I received his size scared me but in the end it is perfectly made for a good grip and therefore less fatigue the hand and wrist. I do not play games so I set the buttons by what I often use: cut copy paste, and me macro function allows to do what I want. The choice of the color of the LED is nice. Too bad it is not wireless but must say that the cable is long enough so it is not annoying. I recommend it for any purpose :-)
