Don't forget, a few purchases are from guys working for the government.
This will not go good for AMT if those guys get burned. (Not that I think they will.)
I, myself, do not work for the government. However, both my parents do. One for the Navy, one for the IRS. Both have also worked for the US-Postal service at times. (Ok, the postal-service is not a horribly strong entity, but it is protected/run by the federal government.)
This will be an interesting few weeks ahead.
Remember, they have been operating for years from the same location. I am sure that if something was honestly askew, they would have been busted by now. Scammers usually don't operate from the same location for years. They move around, to avoid capture. They usually don't dig down and root themselves to one location, for easy capture.
Bitmine.ch (Coincraft) is having similar design issues. That too, is also curbing my advancement on moving forward for a refund. I made a purchase to get a machine. If I wanted to just hold my coins, I would have just held them. We all would have.
If I were them, I would give the refunds, just because the people buying machines now, are buying 1.2THs machines, without the bonus-boards. They would be saving themselves from having to throw bonus-boards into your orders, and buying more time to build that machine. Since the new-order that would be your actual refund, would be a lot-higher number in the list.Not only that, but it gets our orders bumped-up on the list.
That's my business-outlook.
P.S. No need to figure-out how to make the extra 6th bonus board work in that one case... Just send us two cases with 3 modules each... Works for me! (Rather than 6 inside one case.) Also gets rid of your smaller PSU's that you have laying around. I'll still wait for the other design, if you have that coming. I'll take a 2.4THs unit with less modules, so it matches the 1.5THs bonus.
P.P.S. Sell upgrade modules separately. I'll Fill the missing spaces if you do that. Instant future sales!
P.P.P.S. Are you making sure there is an adequate +5v load on the PSUs? Without that, some PSUs can't regulate the +12v rail correctly. Might be the source of some of your power issues. (A 5W wire-wound resistor or just try using an old CD-Drive for a load on +5v. That will put a load on the +5v rail for the PSU. To test it.) If that is the issue, buy some 5v fans for cooling. 1A worth, instead of 12v fans. That or a 5v light for inside the case.
