If all of that fails, i love my MX518 (i know it's corded, but i still love it )

Oh the on board mouse battery police give plenty of warning prior to expiration.

A mouse pad is as useful as the people that use it.
I bought a new mouse pad. The people, aka wife and grand kids, did not want it so promptly removed it never to be seen again.

As a smoker I was used to cleaning the mouse track ball on ocasion. I just never carried that hygiene over to the laser mouse.
It only seems to stand that byproducts contaminate the lens just as it would hose up a mouse track ball.

Ill try cleaning the lens.

Thanks for the tip!
