I think this is the set I have. These are amazing. The button covers stick over top of the joycon buttons and it makes them much more responsive and clicky. My joycon buttons were a little frustrating to push and wouldn't always respond but with these covers, they are fine. I don't have to push harder or multi click, they just work and it's nice to use. I don't know if they just distribute the pressure right or if it's the shape, but they are great. These joystick covers are really nice too. I have a few other sets of the pawprint ones and these don't tend to pop off as much as some of the shallower ones that otherwise look the same. The shape and raised design make it easier to push the sticks around, too.

The single most comfortable way to play hand held on Switch. the crystal part is bendy and then the various grips slide on so you can customize the fit. It makes a huuuuge difference in hand fatigue and comfort. It feels nice in the hand. It can dock in the case, but the case goes around the joycons, so you cannot take the joycons off with the case on. This is fine if you have a second set or a procontroller for playing docked or you can easily take the case off. The one draw back is on one of mine, the triggers are a little more difficult to push.
