I was afraid to buy when 90% of the reviews said that the mouse fell out of my hands, but I have never had anything like this. I am satisfied with the purchase, in combination with a high-quality mat, the sensor opens 100%, I did not observe any disruptions, even the most minimal ones. Different pros: Top-end sensor, convenient location of the side buttons, comfortable shape of the mouse, easy-to-configure software, a wide range of settings, nice and high-quality material, easy to clean from dirt, quite light in weight. Some cons: After three months of use, the wheel began to creak disgustingly. It's barely audible with headphones, but without them it's just awful. After active use, it gets dirty very quickly.
