Purchased 2 BTS7960 Drivers. One driver had a solder bridge across the controller Vcc input and GND causing a dead short. Removed solder blob and then the driver worked. Second driver "half worked" meaning a DC motor could be controlled in one direction only - pretty useless. This company should really inspect and test their products before shipping.
