In general, the rat is not bad, but for almost 100 bucks, I certainly expected the same level of quality. But alas, it disappointed me a little. Although the rat itself is very comfortable, the materials are pleasant to the touch, it feels like a cast in the hand. And there are no complaints about the sensor, everything is fine and very smooth. In this regard, everything is on top. As well as the software for setting it up. If it were not for the parasitic click, I would have put 5 stars, but only a three. He is not particularly annoying, in games and during the day he is almost inaudible, only in the evening in silence. But still I think this is unacceptable for a product of this level.
