I don't normally write reviews but I had to because of how easy they were to install and how well they worked! This is a direct replacement for the awful joysticks that come with the joycon. The drifting on my stocks got so bad that I would never play them again. To help, I bought a Hori Split Pad Pro (also a great controller) and was about to throw away my old joysticks. Then I found her and the rest is history. Installation took 5 minutes per controller if you did everything right. The first attempt wasn't very successful and I ruined the connecting cable on one of them. Love and learn I guess. I hooked up the other three with no problems, and after calibrating them to the manufacturer's recommendation, they work perfectly!
