This is a junk item: a Logitech MX Master 2S. The pointer stopped working, so I replaced it and am now selling this one. Aside from the pointer, the left and right clicks and the scroll wheel function. Also, as shown in the second photo, there is cracking in the rubber on the thumb buttons, and the rubber on the scroll wheel is peeling off, possibly due to hydrolysis, as shown in the third photo. Please understand that this is a junk item in the condition described above before purchasing.
