These thumbsticks are designed for Xbox One gamers who want to replace worn-out or damaged analog thumbsticks. They're made of high-quality rubber for durability and have a concaved thumb grip for better control. The size and grip style match the originals. Use them to enhance your gaming sessions. Just note that installing them requires opening the controller, which might affect your warranty. You'll need a Torx T8 & T6 security screwdriver (not included).
