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

On day one I was happy with the adapter, it worked like clockwork, all I had to do was plug the USB into the Nintendo Switch dock and press the button on the adapter for my PS4 Controller was in Bluetooth sync mode and immediately connected and working. But today, unfortunately for no reason, every time I connect my controller to the 8Bitdo adapter, it connects, but for some reason the controller does not stop vibrating. I'm connecting a PS4 controller to a PS4 to see if my controller is broken, but it worked fine, the PS4 didn't vibrate. Controller and the same problem, it connects to the controller but the controller won't stop vibrating. And it's not a small vibration, it's a rumble, like when a grenade explodes in the game next to you. I think for $20 it lasted a good amount of time, I should have just bought a Nintendo Switch Pro controller for another $40. A: I'm changing my rating from 1 star to 3 because I received a full refund.
