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

Pretty cool overall. Little did I know soldering was required to replace the ABXY. I had to discard 2 pieces to make them work. The notch for the sync button was too big and didn't fit. The left bumper and left trigger conflicted and had to file the underside of the bumper. In addition, during operation, the vibrator weakened, and they began to rattle unpleasantly. I used medical tape to secure them. But for the price it's great and I'm very satisfied.
