Review on Xbox One Controller Joystick Replacement Kit - 6PCS Original Thumbsticks Analog Thumb Sticks Parts - Authentic Rubberized with T8 & 3.0 Repair Screwdriver Kit for Improved Xbox One Controller Performance by Rosalee Rivera

Virtually indistinguishable from the original Xbox One controller joystick. You really can't see the difference unless you put them side by side under a microscope. They work great. Just like the originals. Installation was pretty easy too. Watch a short video on YouTube or just find out. I switched both sticks on three different controllers in about 20 minutes. Really can't recommend enough.
