Candy Con controllers at GameStop - High quality and customizable

These things are the cats meow. They use Hall effect controls to eliminate drift and reduce wear. The faceplates and controls are all replaceable with any of the plates and control colors and designs you want. The plates attach with magnets and are stackable so you can change them out whenever you feel like you want something different.
