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.
