Review on Carocheri 8 Pieces Silicone Cap Joystick Thumb Grip Cover for PS3, PS4, Xbox 360, Xbox One, Wii U Game Controllers - Pack of 4 Pairs by Doug Layman

Works very well with PS4 and also with my third party Gamersir Android controller. HOWEVER, DO NOT try to pry the original PS4 grips off the joysticks. This thumb grip will not fit properly on the PS4 joystick if the original thumb grip is removed. I made this mistake and the thumb grip slipped off one of my PS4 controllers. My 2nd controller, which still has the original grip, has no problems. I don't blame this company, just take my warning.
