OEM Bensu “Thuinderbolt Racing cars” aka Bullets are being sold in the US as Bensu MicroMites. I dont know if anyone already posted this.
Also, another OEM called Speed Dragons are being sold in the US as well. These OEMs are sold in a glass cube similar to the Mirco-X mini Racers, but the base of the cube is NOT the controller. Instead, there is a normal Tomy style controller inside the case with glittery buttons (eww yuck).
