Review on Upgrade Your Xbox One Elite Controller with QINGYA 18-in-1 Blue Replacement Parts & Thumbsticks by Cathy Magel

The product looks cool but it doesn't fit. I just needed a new bumper for my elite controller and it had the screwdrivers needed to take the controller apart which was a plus. After swapping the buttons and reassembling the controller, I noticed that the left bumper is a bit too big for the controller when pressed, so the left and right triggers are depressed as well. I also had to cut off some plastic with a model knife. Be prepared to take the controller apart a few times to get the exact fit.
