Review on 🐱 Cute Cat Claw Design Thumb Grip Caps: Perfect Replacement for PS5, PS4, PS3, PS2, Xbox 360, Xbox One Controllers - 20 Pieces of Soft Silicone Analog Stick Covers by Brett Morrison

They were ordered for my teenage daughter. She really likes them, her only complaint is that they are a bit difficult to put on the controller's joystick. They need to be turned inside out and then stretched. You may need someone to help you the first time. Otherwise they are perfect. She says they prevent thumbs from slipping off during gameplay and are a good replacement for the original caps that came with the PS4 controller. A good product!
