These thumbsticks are perfect for Xbox One gamers looking to replace worn-out or damaged thumb grips. They're designed to fit seamlessly onto Official Xbox One controllers. The concave design provides a better grip, enhancing your control during intense gaming sessions. Made from durable rubber, they're built to last. Just note that installing them requires opening the controller, which might affect your warranty, and you'll need a Torx T8 & T6 security screwdriver (not included).
