Important to me in a mouse two things in particular: First 3 keys, because I'm just "old school". I no longer need and do not like the usual positioning of extra buttons. Secondly, a scroll wheel, which I clearly the "snapping" feel and has a good grip. Both I really like in this mouse. In addition, the mouse fits comfortably in your hand (I have rather small hands). Jerky Compared to my old mouse or does it not a bit, the movements are super fluently and precisely. The surface material I find also very good. It is slightly rough, so you always have the feeling of good control. The only downside is perhaps the illuminated logo. One can find something Poser moderate or childish. But in addition I like to see across, when compared to other gaming mice it's rather decent.
