Review on Replacement Parts Repair Full Set ABXY Dpad Triggers Buttons Kits Controller Mod L1 R1 L2 R2 For Xbox One Elite XboxOne Elite (Purple) by Reggie Stewart

These are a good replacement for a regular controller (maybe) but they will not fit the Xbox One Elite Series 1 controller. The parts are too thick in places that should be thinner; The bumpers are a different length than the originals, so they will not fit even with the original cover center piece. Haven't tried other parts to see if they fit or not.
