A typical backlit office mouse. It served for about a year and a half, it broke by accident, but when I wanted to pull the mouse towards me, the cable (!) came off the mouse (maybe pulled too hard, xs) I would give three stars if the mouse did not position itself as a gaming mouse. As an office mouse, very much, as a gaming mouse - complete crap. Has pros: Beautiful lighting, pleasing to the eye at night Ergonomic shape, very comfortable in the hand Change DPI, for each color Cons below: Not a gaming mouse from the word AT ALL. Sensor breaks down If you raise the mouse in the air, the sensor will shake and your teammates will think that you have epilepsy (there were a couple of such funny moments)
