The Mutual Power Hercules 690 clone history:
In 2008 the Mutual Power's supplier (Xpider Co.) copied the mounting system of the Eagnas Smart 707, copied the unidirectional clutch design of the Eagnas Challenger I, then copied the turntable and swivel clamp bases of the Eagnas GC to create the Hercules 690 model.
