Apparently you can take your XBox controller apart and swap out different parts. I purchased some textured back panels for my controller that provide a better grip. I like that it is textured and not just smooth because I feel like it will slide out of my hands if it is just smooth.
I also picked up a kit to replace the thumbstick controller within my other controller. I am going to have to pick up a soldering iron as well but It will be an interesting thing to try and fix.
I’ve had my Xbox for about 2 years now. When I bought it I also bought a second controller so that the kids could occasionally play with me. Both controllers have been perfectly fine in that time. However, I have probably run them ragged in the past year from all the gameplay I have done. To that end both of the controllers failed on me. They each have their own issues. I detail them in this video below. Because I could not make videos with controllers that would act up out of nowhere I bought a new one. The cost of he business of play. I got the Shock Blue controller and it is really nice.
