AirTV is a good company, they back their products.  They emailed a prepaid UPS return label, will ship out a replacement when they receive the defective unit.  I hope I haven't jumped the gun with praise before they've shipped out the replacement but I don't think so.  At the very least I was expecting to have to pay the return shipping.  I'll let you know the turn around time.  Defective unit went out on 1/11/19, expected delivery is Tue 15th.  They even sent a 2 day delivery label (went out on Fri so you've got the weekend to contend with) not a slow boat to China label.  So far so good.
