8bitdo Zero Small Bluetooth Controller This is an ultra-small wireless gamepad. When connected to a PC via USB, it's recognized as having a huge number of buttons, but the only ones actually usable are the D-pad and eight buttons. I bought it new on Amazon in 2017. The product name at the time of purchase was: FC30 Series - Ultra-small Controller "Zero GamePad" (Color: White & Blue) (Size: approx. 7.3cm x 3.5cm) (For Android/iOS/Windows/Mac OS) Retro Game Controller Wireless Bluetooth Gamepad Dianzi Original Version [CXD0977] [Import]
