This is EXCELLENT. They hold up well, provide a good grip and go a long way in repairing broken thumb pads. The problem is related to the product it was intended for, Switch. If your controllers are in some sort of protective case, no matter how thin, the analog stick's head is too wide to move properly when it hits the case. Aside from that subtlety? They will stretch to fit older GameCube and PS2 controllers. Honestly, anything but a GameCube C stick. I'm excited and impressed. GREAT for fixing analog sticks! They don't even move!
