Review on 🎮 eXtremeRate ThumbsGear Adjustable Ergonomic Thumbstick for PS5 Controller, Compatible with All PS4 Controller Models - 3 Heights, Domed and Concave Grips, Black by Daniel Ton

Pros: Easy Installation. Works perfectly with PS4 Kontrol Freeks. (If you play a lot you know what I'm talking about). The ideal size is maybe 2mm higher than the original PS4 height. Xbox equivalent. Nice and grippy, concave and curved textures. The vertices actually stay on very well with the adjusted friction. Cons: I'm not sure how long it will hold the set friction with frequent changes of tops.
