I had three old Xbox 360 controllers that I couldn't play with because the rubber pad was worn out. I replaced both grips on all three with this kit. Having the screwdriver for it was extremely helpful and made it much quicker and easier to remove all 7 screws (don't forget the ones behind the sticker under the battery compartment). I was also able to clean up the junk that had accumulated over the years. My controllers are like new again!
