Review on 🎮 Enhanced Bumpers Replacement LB RB Triggers Repair Buttons | Premium Quality & Long-Lasting Craftsmanship | Includes T6 T8 Screwdriver Kit | Xbox One Elite Controller Upgrade (2 Pack) by Mark Callaham

Installation is not easy but the tools provided at least allow you to open the controller without damaging it. You need to find a manual on Youtube, no instructions are provided. Finally and very importantly, the bumpers are shaped differently than standard bumpers and have sharp edges between the bumpers and the triggers. This is a small detail but very noticeable. I don't know what the long-term games will be like, but it's a bit awkward. However, they work. They fit the controller well enough in a pinch, but I might look elsewhere for better bumpers.
