Gbros Wireless Adapter for Nintendo Switch - 8BitDo

Took about ten seconds to set up and the input lag is barely noticeable, even in Smash. Being able to dust off my old SNES controller for Mario Kart was a fun little nostalgia trip that I didn't expect to work this smoothly.

Plugged my old Gamecube controller in for some Mario Kart and it just worked, zero lag that I could notice. The fact that it also handles the NES and SNES classic pads makes it a nice little bridge for my whole retro collection.

My Wii Classic controller finally gets to live again on the Switch, and the lag-free connection makes old Mario Kart sessions feel just right. Setup took less than a minute, and I love that I can keep using my original wired controllers instead of buying new ones.
