Yes, because it's totally fair to ship faulty equipment to your customers and then tell them they need to pay to ship it back due to not taking the time to test before shipping.  I don't know how much it would cost to ship these back to Hong Kong or how long it would take to get them back, but I do know that any hope of ROI for me is long gone.  At this point, I think it may be best to just take the loss and not continue wasting time troubleshooting as well as throwing good money after bad.  I know from the lack of responses, that is what asicminer wants to see.
