Ximimark 2Pcs BTS7960 Stepper Motor Driver Module High Power H-Bridge PWM Driver Board 43A Current Limit Control Module For Arduino Smart Car

Out of the two drivers that arrived, one of them worked and the other one blew the transistor to pieces when I powered it up. Upon closer inspection, the legs and solder pads were skewed to one side and the pads were shorted. I'm reading 86 ohms between a pair of the pins. I wish they'd find a more reputable manufacturer to make these because the BTS7960 is a great little driver when it works. But I've had more than a 50% failure rate overall. These had different silk-screening than the other listing I tried (selling individual 7960s), but the quality was about the same (crooked components soldered onto the PCBs).
