Review on ClouDream Switch Gamecube Adapter for Wii U, PC, and Switch - Plug-and-Play Choice for Super Smash Bros and Gamecube Controller by Jeff Leu

I bought these controllers/adapters mainly to play games with my siblings. They are great for Smash Bros, but you have to take into account that some of the Switch titles are not compatible with this style of controller (Gamecube). But overall the adapter works great with the controllers and I haven't had any problems so far!
