A perfect Gamermaus must have exactly what this mouse! Pinglose or delay loose connection! In addition to the hot keys that can be used not only in MMORPGs, I like it very well the software and operation of the laser mouse. One can very easily adjust the sensitivity of the mouse (up to 5600dpi), earlier this was a dream for me, now it has come true! Razer bring many great mice on the market, but this is just awesome. Looks visually from really horny and fits perfectly in your hand! Each button is easy to reach with your fingers and after a few game days you learn to use it quickly. This mouse is only recommended for every gamer right!
