Review on 🎮 Enhance Your Gaming Experience with SUBANG Silicone Noctilucent Thumb Grip Caps - Compatible for PS3, PS4, Xbox 360, Xbox One - Analog Stick Caps Replacement by Katrina Dorsey

Fits all my controllers - PS4, Wii U Pro Controller, Switch Pro Controller, Wii U Gamepad The fit is snug and gives some structure to the thumbs. I can't say it improved the controllers drastically, but it did eliminate wear and tear on the thumb grips and added extra grip as well. I don't know how well it will hold up after long term use, but I'll update my review in a few months. But for now I'd say it's doing its job well.
