My cheap-o RadioShack optical mouse is suddenly acting terrible and sticky. Dammit. I mean, it is a cheap-o RadioShack optical mouse, but I've only had it for like a month.

I found a cheap-O GE optical mouse in a pile of old computer junk in my room. I think I got it for christmas one year and I was like, WTF I don't need a mouse, I have a laptop with a decent trackpad. But now it's useful!
