KontrolFreek Call of Duty: Modern Warfare III No-Slip Thumb Grips - Universal Gaming Controller Accessories for PS4, PS5, Xbox One, Xbox Series X & Nintendo Switch Pro Controller (2-Pack) - Improve Grip & Accuracy for FPS Games

I love these grips. I have an Astro C40 controller with the standard tops and battle beaver joysticks (increased tension). I love my astro thumb tops as they have some nice bumps but I still found my thumbs slipping at times while aiming or turning and aiming etc. My brain knows what to do, but I slip from the no grip.Enter the Kontrol Freek Thumb Grips. I initially had trouble attaching them so I took the thumb tops off the controller (they pop off) to more easily attach and seal the thumb grip. Took less than 5 minutes. My K/D has already gone up .05 in 10 games. I am impressed. I am able to turn and shoot much more quickly, those close gunfights I'm winning more of them because of my increased control. I find them to be very comfortable to use and am extremely pleased. I have some other KF products (HDMI, an ethernet) and everything from them has been great, high quality.Thanks and have fun!
