Works very well. I broke one of my joycons, the joystick was dented and some of the cables came loose and this kit gave me a new joycon and I was able to fix it easily with the tools. And the tiny little screwdriver is magnetic so you can't lose your screws. I broke it a second time because I charged it and dropped it and then the tools still worked. This has saved me from buying a new joycon twice now. So I definitely recommend it if you have hardware issues. However, I don't know if this helps with drifting as that's not the problem I was having.
