Review on Silicone Replacement Thumb Stick Grips Caps Cover for PS4, PS3, PS2, Xbox One, Xbox 360 Game Controller – Analog Controller Joystick Upgrade by William Sanchez

3 stars only because they arrived quickly and were cute. But other than that, they're a bit lame. They were only on my controller for a few minutes because they kept popping off during gameplay and I couldn't use my joysticks to trigger while they were on. Nice idea, but not for me. Maybe they work better for people using control freaks.
