They are good for what they are. They look pretty cool and are good for a little extra support. They don't add much height and the notches are the only major thing that improves traction, but it's not overwhelming. I would still recommend them if you want to add some pop and a little more grip to the JoyCons. I wish it was a thicker material that feels more grippy than it actually is, but can't complain for the money spent. for a pretty good product!
