Review on Fosmon [Set of 4] Xbox One Analog Stick Joystick Controller Extended Thumb Grips for Enhanced Performance in Solid Black by Anita Davis

The original rubber joystick on my XBOX ONE controller wore out after a few years of repeated use. I bought these replacement pads to repair my left thumb pad. When I received them I attempted to install them and realized that they are NOT SEAL REPLACEMENTS - they are designed to replace existing rubber pads to reduce wear. I wasn't happy when I first tried to use them, but after re-reading the description I realized my mistake. I can't blame the manufacturer of this product for my misunderstanding, but I think I should warn others. (I was able to solve my problem by putting a small piece of tape over the existing thumb grip and then attaching the rubber cover. Looks like it's holding up well so far. Only time will tell.
