Mighty Mouse Ball

[magicjames92]

The ball on my mighty mouse wont scroll down, this is the second mouse ive been through. It was lightly used, and died in a couple weeks. Is there a quick fix or something for this? it still scrolls up.

Turn upside down on a piece of paper and scroll vigorously.

i went through 3 of them the 4th one i finally took apart myself cause i was tired of it and apple wouldnt replace it anymore. there are rollers like in a regular ball mouse that get dirty inside. however i havent figured out how to put it back together again so dont go taking yours apart.

Mine used to have lots of problems so one day I took it all apart following some guide and cleaned it out. I broke the bottom plastic Rim but you can't tell. Since then it hasn't had any problems

This works 99% of the time. I have done it for years.
