Review on Improved Joystick Thumb Stick Key Caps for enhanced gaming experience on Sony PlayStation: Hapurs Anti-skip Silicone Replacement Joy Stick Controller Shell Cover Protector for PlayStation 3, PS4, and Xbox 360 by Brooke Parker

I can't play without them anymore. I use the highest. They hold up really well too, unless your controller gets stuck between the pillows on the couch or a toddler decides to chew on it. They loosened up a bit after being slid a few times but I love them so much I just put a drop of crazy glue on the rim. I'll never play without her again, so I don't care. The smooth and ultra-precise thrust from them is amazing, and the hand position on the PS4 controller has been greatly improved.
