After dealing with my happy cons dangling and coming loose from the screen and controller connections I bought these clips to keep them in place and place to install. They work fantastic and give a much better metallic click to a traditional switch lock. That's very pleasant. However, I will say not for the intention of dissecting the joys of the minuses. When you take them apart, make sure you know what you're doing. Otherwise I would leave it to whoever has done it before. There are very fragile parts inside the joycon, and opening it incorrectly can cause more problems than before this update.
