There is no need to buy it. I regret what I bought and feel worse. I bought plastic that looks like rubber, but it is actually hard. It hurts after a while. A friend's hand is relatively large, and even the joints will get stuck after wearing it, and it is even more unnecessary to have a five-hole one. Imagine making a fist. Wearing this grip is obviously a state of loose fist, which greatly affects the strength of punching. So there is no need to buy accessories to play joy con.
