Glad to hear about your wife's health improvements.

As for the 33% refund I'd say it's highly unlikely, Bitmain has very weird "scamy" rules regarding DOA and warranty, if you claim that this was DOA, then they will say that 30 days have passed from the day they shipped the miner, assuming shipping from China takes 10 days, you have only 20 days to act, if you take more than 20 days to send it then it can't be treated as DOA anymore, so even if for some reason DHL, FedEx or whoever your courier may be fails to deliver the miner under 30 days, and say you get it 31 days after it's shipped, and it arrives dead, Bitmain will refuse to treat it as such because their rule states the following:


If you decide to go for RMA, on all the new models you MUST ship the WHOLE miner, you might get lucky enough to be asked to ship only the bad part such as a hash board, but Bitmain reserves all the right to tell you that YOU were the one who toasted the board and that they owe you nothing.

Bitmain warranty is a joke, they know that most people will rather keep a half-working miner than waste time returning it and wait for the replacement to arrive due to the nature of mining where time = money.

Having said that, I noticed that being persistent can sometimes (actually seldom) grant you some sort of compensation (in a form of coupon/s) without having to send the whole miner nor the defective part. That of course, depends heavily on your purchase history and the mood of whoever is handling your case  .
