Had this controller since July 2019. Not only is it built like a gamecube controller, which is perfect in my opinion for smash, but it also has extra buttons that a pro controller has, that allows me to fully utilize my switch from the controller, such as capture, home button, plus, minus, etc. It also has zl and zr buttons, which let me play games like breath of the wild, which I can't play with a normal gamecube controller. As for smash, this is PERFECT for me, I don't experience any mis inputs or any lag like any of the other reviewers are commenting. I especially enjoy the fact that its wired, because it provides a sense of security for me for the fact that I dont have to worry about batteries or charging it. Great controller overall for the switch. would buy again.
