KontrolFreek Precision Rings™ are made from a unique material that adds resistance to your stock thumbsticks (compatible with PlayStation 4 (PS4), PlayStation 5 (PS5), Xbox One (XB) & Switch Pro) so you can take more accurate shots, even at max in-game sensitivities. They are highly elastic and antimicrobial, so you can use them again and again. If you love our Performance Thumbsticks®, Precision Rings are fully compatible. Try combining them with your favorite Performance Thumbsticks to max out your sensitivity, and take your game up an extra notch.
