What mouse have you used that didn't break?
All of the mice I've used had problems, either the side click buttons break, the left/right click button clicks by itself or doesn't even register a click, or the scroll starts to glitch.
But anyway what mice have you used for more than 4 years and still is working great?
Also my next mouse might be ENDGAME GEAR OP1 if anyone had problems with it let me know.
