Review on 8Bitdo Wireless Bluetooth Controller Adapter Converter - Nintendo Switch/PC/Android/Raspberry Pi Compatible with OTG Cable (Grey) by Michelle Linares

The key itself is bulky. It's very difficult to plug into a USB port when other things are plugged in next to it. It worked when I first got it, but stopped working once I got into the actual game. I updated the firmware (which is also painful and unintuitive) but it still works and turns off. I return this and would rather buy a professional controller because of the many workarounds you have to do to get this product to do what it says on the tin. Instead I get a Mayflash key hoping it's better. DO NOT RECOMMEND, SAVE MONEY AND TRY OTHER OPTIONS.
