8Bitdo Gbros. Wireless Adapter for Nintendo Switch - Compatible with Wired GameCube & Classic Edition Controllers - Seamless Wireless Gaming Experience for Nintendo Switch - Perfect for Smash Bros, Mario Kart & Retro Gaming Sessions

This product is amazing. I had looked at it before but didn't really understand what it is. This product turns wired controllers into wireless Bluetooth controllers that can connect to the Switch or to Windows. On the one side you can plug in a wired GameCube controller. On the other side you can plug in any controller that uses the type of plug found on the bottom of the WiiMote (but obviously not the Nunchuk attachment), which include Wii Pro Controllers, NES Classic Controllers, and SNES Classic Controllers. But, you may say, not all of those controllers have the same buttons as the Switch controllers. And this is where the buttons on the GBros Adapter come in handy. It has the buttons that you lack for the Switch. For example the GameCube controller maps the start button to the Plus button, and the red button on the GBros is the minus button.But how does it work? I hooked up my wired GameCube controller and played Smash Brothers on my Switch. It was glorious. No noticeable lag and I layed the law down and delivered a sound beating to computer controlled characters for a couple of hours. (Granted I had them on a low setting, but even then multiple characters can get chaotic.Besides, I was looking to give a beat down not me challenged. But even when I upped the challenge the GBros Adapter was flawless.) Fun, fun, fun. I highly recommend this product. I have four now.Someone may counter that you can use the GameCube adapter for the Switch. I have that product and it works just fine. But I have to borrow my WaveBird receivers to make that happen wirelessly, which is okay but still a little cumbersome. I also have to use up the two USB ports on the Switch. The GBros Adapter is just quicker and cleaner to get going on my Switch. It doesn't mean I am against using the GameCube ports unit at all. I have one for my Wii U and my Switch. It's a great little product. But getting to turn my wired controllers into Bluetooth Wireless controllers is just priceless. Plus it gives me options as well because I have 3 different types of Wii Pro Controllers. And it can be used on Windows as well. If you're on the fence, buy one. Connect it up. Play some Smash Bros or whatever game you like that uses a pro style controller. Let the smile on your face make your decision for you.
