Review on Nintendo Switch Joy-Con Controller - Black Skull & Co. Skin, CQC and FPS Thumb Grips Set Joystick Cap Analog Stick Cap, 3 Pairs (6pcs) by Keith Leach

A little tricky to attach analog sticks. It took me several attempts to center and properly adjust them. My favorite of the three, the medium-thick cap with a concave thumb surface, doesn't work on a real joystick because it places the analog stick uncomfortably close to the ABXY buttons. .Overall I haven't noticed any improvement in my gaming performance, just a slightly more comfortable grip. Is it worth your money? If you have big hands and use handheld or joy-minus a lot, maybe.
