Cleaned Mighty Mouse

My Mighty Mouse has become too old and the its scroll wheel has already got stucked for months. Yesterday, the wheel finally completely not move. So I decided to repair it. The work is not hard, first take the back shell apart, the scroll ball might require a rather small bolt driver however.

After cleaning the ball, I found I could not install the back shell back... Maybe it is time to buy a new mouse. (BTMM preferred...)

By the way, here is more about the mouse's scroll wheel I read somewhere last year, and it might be interesting to you. The scroll ball's gear-turning sound (the sound you heard at scrolling it) actually was not caused by the ball itself, but comes from a tiny speaker inside the mouse. Just unplug the mouse and try to listen to the wheel scrolling!
