I really liked this mouse. I don’t understand why many people complain about the wheel, they say it either rubs against the body, or it doesn’t work at all. I have no problems with this. With its pros: 1. Convenience. In the hand, the mouse is just perfect. 2. Durability. I have already dropped this mouse and hit it on the table, and it is like new after a year of use. 3. Fast and comfortable sensitivity switching. 4. Excellent accuracy. Some cons: 1. Sometimes the sensor just seems to turn off. But most likely it's not because of the mouse, but because of the carpet.
