Review on KontrolFreek Modern Warfare - High-Rise A.D.S. Performance Thumbsticks for PlayStation 4 (PS4), Transparent/Black, Concave by Heather Gorman

They will not fit Astro C40 joysticks without much force damaging the joystick by scratching or tearing the joystick's rubber pad. A brand new controller and the photo shows what happened to my joysticks when I tried to install them. I ended up tightening it using excessive force, but it's tight and now non-removable, and the design is offset to the side so it doesn't fit my thumb. Astro C40 owners DO NOT BUY THIS PRODUCT. KnotrolFreek you need to promote this immediately or work with Astros and make the ones that fit. This is unacceptable and your website does not indicate that this controller is not suitable. Dissatisfied, to say the least.
