Nothing has ever spilt on the mouse. I tried using a compressed air can on the mouse wheel and the issue still persists.
Is there a way to open the mouse up?
There's a certain point in a full 360° rotation downwards where the scroll wheel becomes hard and rough to move. The mouse wheel feels fine when scrolling up.
Had the mouse for a couple of months now and just started to have this issue.
Any ideas how to fix this?
