These controllers worked flawlessly as soon as they were synced up with our PS3. My kids (ages range from 4 to 11 yrs. old) primarily use these to play games like Little Big Planet 2 and Lego Marvel Super Heroes and Lego Avengers, etc. For the first month, there was no problems. But then the pink controller began having response issues with the controls on screen. It became defective and unresponsive although it would power and still take a charge just fine.
Fortunately, after a few weeks of correspondence, the manufacturer awarded me a partial refund for the one controller that no longer works properly. The blue controller still works great. My only issue is that as soon as you unplug the controller from charging on a USB cable, it instantly wants to ping and boot up the PS3 on it's own. You either have to unplug the PS3 so that it doesn't respond to the controller OR just charge the controller out of PS3 range. Other than that, it charges and retains a charge just fine for hours of gameplay.
Would by from again in a pinch, since these controllers are only a FRACTION of the cost of the Sony Dualshock 3's.
