Does anybody have any idea on how to disassemble this mouse? I’d like to replace the switches inside of it, but I can’t seem to find any screw holes, even under the feet of the mouse.

The M280 has a single screw below the battery. It is covered by a black sticker somewhere in between the + and - signs. I scratched the area with my nail and a circular area appeared indicating a screw hole. I removed the screw and the was able to take the thing apart for cleaning. Hope this helps.

Hi Yang Ho There should be 2 screws where the legs are and one next to the battery. I haven’t personally open one of them but I have opened different ones. Hope this help
