Great option for your money (I took somewhere for 2k) Has pros: The mouse is excellent, fits comfortably in the hand, light, sensitivity is adjustable. It was recognized by the Raiser software without any problems, and by the way, the brightness of the backlight is adjusted there. Some cons: If you scroll a lot and quickly (for example, a web page), the wheel starts to creak, which is annoying. If you need to scroll a little - everything is ok, it goes smoothly. Judging by other reviews, this is a common problem with this model.
