Review on 8-Piece Analog Controller Gamepad Thumb Stick Grips with Antislip Thumbsticks for PS5, PS4, PS3, Switch Pro, Xbox One, Xbox 360, Wii U, and PS2 Controllers - White by Tyson Mosucka

Unrestricted. The shape doesn't fit the top of the Xbox One controller. Xbox One controllers have a convex top, but the inside of these covers is concave. It leaves a large empty space in the center and feels soft when you press it with your thumb. I suspect they were made for a different type of controller. Wouldn't recommend it. There are other products that look similar from above but are correctly shaped on the bottom for Xbox One.
