Product review (2 stars): it's really easy to return stuff on Amazon
The start device had a "rattling" noise out of the box.  I measured an open circuit between the start and run pins, which appears to mean it is a defective/broken part.  I connected it anyway, just to give it a try, and it had the same issue as the previous start device.  Thankfully, it's really easy to return stuff on Amazon, which is why I gave this 2 stars instead of one.
