Did the RB button break on yours? That is what happened to mine.
My left stick drifted to the right probably immediately, super irritating and pathetic. I think the A button didn't respond sometimes.
I'm still thinking of getting the Rock Candy but I can't get the thought out of my head that the prices most likely will plummet "soon" with the next Xbox coming. I'm also a little bitter with all the crazy PS3 controller deals and we can't even get a wired 360 brand name for less than $34. Also can't trade in my wireless 360 for crap either :( Why is the PS3's Rock Candy $15 and the 360's $25 too
