I LOVE them! I've had them since January of this year to replace my old Animal Crossing button caps after seeing Geekshare start selling the caps. These are hard plastic caps that you attach to a flat piece of cardboard over the joycon buttons using self-adhesive stickers. Removing the sticker cover can be a little tricky, but once installed the buttons stay in place. I have both analog and regular buttons on both of my respective joycons and they are very responsive. The analog joystick was a bit stuck at first, but over time it worked. The paw buttons also don't stay in one place and tend to curl around the button. Apart from these small imperfections, this little button with a paw motif makes me happy. They are the perfect complement to my Switch.
