Very good gamer mouse

This optical mouse is in the lineage of optical gamer mouse (Logitech MX518, Razer Diamondback). The choice of optics may seem antiquated face of current lasers, however, it would allow better management of movements, mainly for players using a low sensitivity (large displacement). Personally I have not received an advantage compared to a conventional laser.

+ Product: good grip, soft touch, two buttons on the thumb wheel good, not too geek, high accuracy, light.
- Product: no end to the sensitivity setting, no change dpi on the fly.
