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 Rachel Scott

In general, these joystick cases are good and match the PS4 controller. I'd say I use them about 60% on my old controller that has worn out the left stick cover and about 5% on my newer controller. I didn't use the large joystick covers as they seemed quite cumbersome at first, but I think if that's what you're looking for they will do. The covers feel clunky, don't fit the joystick snugly, and tend to come off about a dozen times during gameplay. Clumsiness can result in less accurate directional input until you make adjustments. I can't say if they would be better suited to a different system controller as I haven't tried it yet. Overall this is the epitome of a product that I would give 3.5 stars if I could. Relatively affordable (you get a couple of kits too), generally does what the product description suggests, has some flaws (chunkiness) but not worth the hassle of returning it and will be used from time to time. It should be noted that most of the games I use these for require quick and precise movements (sports and shooting), which probably adds to the feeling of clumsiness. If you are a racing, puzzle, strategy or RPG lover then most likely this will not be a big problem.
