These thumbstick replacements are designed for Xbox One controller users. Whether your original thumbsticks are worn out or damaged, these are a great solution. The thumbsticks are made of high - quality rubber, providing a durable and comfortable concave grip. They are sized and shaped very similarly to the original thumbsticks, so you won't notice a big difference when using them. However, installing them requires opening the controller, which might affect your controller's warranty. You'll need Torx T8 and T6 security screwdrivers (not included) to do the installation.
