Works pretty much as advertised.
I bought this to play Hollow Knight on PC, not knowing that the dpad is considered an axis rather than four buttons. This pretty much made the Switch Pro controller useless for that game, but the adapter works well enough. It's not as simple to use as the Wii U or GameCube adapters, but it does seem to work well enough. It comes with a USB to mini(micro?)-USB-C cable, which is nifty. I've really only tried to use it on my PC, so I can't rate its functionality otherwise. The only reason I won't rate it five stars is that the firmware updater doesn't work on my OS.
