I really like my logi mouse, it's held up well with only minor wear after a couple years. the only thing is recently one of the side buttons has developed a mind of its own and will randomly act as a back button no matter what it's set to. like I have it set to act as the middle button but it's like a 50/50 chance it will actually function that way or send me back a page. really annoying and I can't figure out what's wrong with it. don't want to replace it cause I'm broke but I might have to.

also didn't realize how dirty it was until I took a picture with flash lol, it does not look like that under normal lighting. damn. I thought it was clean.
