Does GS even check and clean their preowned controllers? Ordered a blue Dual Shock 3, as I need a replacement for my PS3. Got it yesterday and hooked it up to sync to the console. Then it proceeds to act like it has a mind of it's own, moving through the main menu and pressing X randomly(it turned off the console twice doing this). So don't know how that passed a QA check at a store or warehouse.
After a google search, it's apparently something to do with the gunk that "sweats" from the rubber of the analog sticks. Taking it apart, used a q-tip w/ rubbing alcohol and cleaned off the analog sticks and the rubber pads for the buttons(as the gunk covered most of that pad). After spending 15 minutes making sure everything was put back right, tested it and apparently fixed it(fingers crossed it stays that way). Still can't believe GS sends out stuff that obviously isn't tested.
