I have a controller here which squeaks when you use the R2 or L2 buttons. Like plastic on plastic rubbing sound. I also think this controller was one provided with the new PS3 so might have a warrantee claim I can approach Sony with as I have only had it for 2 months. Does anyone else have this issue at all with their controllers. I have another 5 controllers and none of them squeak like this one and some of them are original Aussie release controllers.
