These buttons kept moving or bouncing when I tried to play Splatoon 2, even though I made sure they were installed correctly on the joycons. If you play any action games I wouldn't recommend it. Although they are really cute. Update: After about two weeks, a fingertip on the pink handle began to tear. I've since ordered another set of thumb grips from a different brand and they've noticeably improved - they don't come off when I'm playing Splatoon 2, even after a few hours of non-stop play. So if you don't want those particular pinks and blues, I don't think these LeyuSmart pens are worth buying. For the record, I used them on the regular Switch joysticks, not the Switch Lite mini joysticks.
