High response gaming mouse, you can't tell the difference between it and a wired one. The mouse is very clean and almost new, and its battery lasts over two weeks. Reason for selling: I'm just trying the next version, and after testing, I didn't see any difference because it has the same speed and response as the one offered + the offered one has a button to change the sensor, while the new version I currently have doesn't, it requires an app. So if I could turn back time, I wouldn't have bought a new mouse and would have stuck with the offered mouse. I strongly recommend this mouse! (I bought it for 550 SAR) I will sell it for 200.
