Well I opened it up as soon as it arrived. I was surprised because it's well made just by touching it. When I put it in both sticks of my PS4 controller it looked and felt amazing. My two controllers (replaces 4 sticks). As you can see from my attached photos it no longer has the original rubber so the replacement Fosmon caps fit perfectly. Note: Without the original PS4 rubber, you will feel a "slack" around the replacement rubber. Weakness is not noticeable, because for me it is just normal. However, if you still have the original rubber on your controller, the Fosmon replacement rubber is HERE. YES, BETTER if you have the original rubber on the joysticks of the controller and it is highly recommended to cover it with Fosmon. 5 stars and 2 thumbs up for me! Absolutely great product!
