Still got a Roller Ball mouse hanging round someplace.
These mice needed regular cleaning, The little rubber ball would pick up every bit of crap within 20 metres. You need to take the ball out and clean in alcohol every now and again. The 2 little roller bearings the ball acted on became encrusted with, what I can only assume was, the crap mentioned before together with a sludge of human grease that had become hardened to a cement like strength.
The only time I can safely say 'I'm glad the ball are gone'.
