Review on 2-Pack Replacement LB RB Bumpers Triggers + T6 T8 Screwdriver for Xbox One Elite Controller Repair Parts - Silver | Compatible with Xbox One 3.5mm Controller Bumpers Replacement by Josh Lockhart

Replacement bumpers work well and it's nice to get an extra kit plus screwdriver for the same price. However, the tiny holes on the replacement parts are in a different part of the controller (the casing around the Xbox Guide button) and both of my replacement parts were too small. I took a 1/16 diameter drill bit and drilled holes to make them a little bigger. I didn't use a drill, I just twisted the drill in my fingers and it worked.
