I have kids. They get crap on my controllers. My other console's don't usually have problem but for some reason my PS3 controllers get sticky buttons. I depress the buttons and they stick for a second. The ones that do this the worst are the shoulder buttons. I have 4 controllers. One became completely unusable, another is annoying, a third is functional, and one is perfect (it's the newest). Anyone else have these problems and have a suggestion for a fix? Why does this only happen to the PS3 controllers? Are the buttons too shallow into the base of the controller or something?
