It didn't work. I have previously repaired Xbox controllers for the same bumper issue and have never had a problem. After receiving them, I could tell that something was wrong. The material is off. I believe they can be 3D printed. However, I installed the bumpers as usual and found that they didn't "click" like they were supposed to. I tried again, same thing. Switched to the second device, same problem. After an hour of trying, I reinstalled the old broken bumpers. They stood up and snapped into place (still broken but at least I knew it wasn't my fault). I gave up in frustration and ordered a set of original Newegg bumpers, which I was originally supposed to have. I received my Newegg bumpers today, they are 100% authentic and didn't take long to install. Do not order these, they are not genuine and could potentially damage your controller. They won't work.
