I sent 7 APW9s to Myrig back in April, they said at the time it would around 2 weeks to repair the power supplies. A few weeks after they received them, they said they were waiting for parts to repair them. Fast forward 6 months, they still said they were waiting for parts so they declared them "unrepairable" and said they were going to return them to me, which at least they did at their own expense. The last communication I had with them was a week and a half ago, so they are there and receiving email. Looks like they are just ignoring new requests.
