All parts are too bulky (yes my controller is compatible) to fit properly. Most can just be slid back into place and you'll be fine. For example, my analogues had to be put in, but they work. However, R2 doesn't work at all. The little pin that the trigger uses to lock is too chunky, so the little spring isn't enough to hold it up when you pull it. I'd give it 2 stars and just keep going, but the triggers were the big selling point here. will return it.
