Probably my friends' fault.

That really messed my friends up!

No longer am I just smashing local friends

A friend of mine was skeptical about this product when he was looking to buy a second adapter (he was able to get an official one) but I cleared all doubts in his mine when he came over and we used the Mayflash.

My good friend has the Nintendo made adapter, which I have used numerous times, and this one operates identically

My kids and friends love being able to use the old gamecube controllers to play it was a good purchase

I bought this because my stingy friend wouldn't buy pro controllers or an adapter for Smash, and we have gotten SO much use out of it, not only for Smash, but for playing emulated GameCube and Wii games, and for Pokken Tournament

Now friends and I can play Smash with our favorite controllers!

Flawless I/O device on the Wii U, and after you get the controller config right, flawless on the PC too, assuming you're not expecting it to do rumble.
