Review on Fosmon Performance Thumb Grips for PS4, PS3, Xbox One, Xbox 360, Wii U - Assorted (8 Pairs) - Enhanced Analog Stick Joystick Controller Accessories by Antonio Cameron

I bought these for my Xbox One, PS4 and Switch Pro controllers and these grips fit all of them! They seem to work best on PS4, but I haven't tested them in detail. You can easily slip off the Switch controller in the middle of an intense game, but that's not too bad. Once you get the hang of it, reinstalling them will be very easy.
