They fit the joysticks well and don't fall off (have been playing with them for a few months now) and look good. I can't say that they necessarily contribute to the "performance" of the game, but I will say that they allow your hands to feel a little more comfortable (so maybe that adds something). I have big hands (6ft 4in tall). Finally, the color is white, but be aware that they are a bit off-white. On a controller other than white, you'll never know.
