My husband is gamers, thus the controller is in daily service. Already after a short time crumbled the rubber coating of the sticks. Then began the complain to (of course, because as a controller so has its price :-)) So off to the PC and to Amazon. Was quite fast find and immediately ordered a pack. Prompt delivery was there and I gave my already an annoyed treasure. We were skeptical whether it would fit at all but keep them properly and through the tiny nubs you slip not from (n) !! Are very satisfied .... yes and what can I say ... my husband is back Happy :-) ends well - ALL IS WELL
