We do NOT have any authorized distributor now. Please be cautious.Reviews from some trustful members will come out in 1-2 weeks. Orders will be accepted after that.
The miners currently in the market are not made from us.Part of the first order (60T) is already in mining bitcoin, see the profit

Now they are in production to fill the order for 1200T.
On and after Mar 1, more miners could be added to the pool.
1. The chips out of Foundry at last Dec. 28, and our sample system came out at Jan, 5.
2. Around Jan 23, we started first batch of the sample systems (totally 70) manufacturing and before Chinese New Year, 60 of them went up online.
3. Our first order is 1300 systems, so we were not daring to do mass production BEFORE the stability test finish. Otherwise if any defect on the PCB boards, then you have to dump a large amount to PCBs (that was what Bitmine did).
4. After things proved to be right and long Chinese New Year holiday was over, we started the big production.
5. During this time, some guys were able to get our original designs ( this is China, LOL), and begun producing their sample units.
6. So since our current production were already paid for, so the next available units will come around March 15/25 time frame.
7. Even thought Bob contacted with me first, but apparently someone tricked him into what he believed the system were from us.
8 .Those systems were sample units made by copycats and NOT from us. Period.
9. Friendly advise: Bob, DO NOT attempt to over clock, you will burn the chips.
10. We will give a production presentation in next Weds. day (Shanghai time), and one thing is for sure, those sample units you received never went longer period of testing. Neither some parts on their board are up to the standards you like to see, so I have to say "Good luck".
11. If you are lucky enough by chance and those parts turn out ok, the max you can go probably around 1T. But the max our system can go is around 1.3T.
Chip related: Innosilicon should have right to sell the A1 chips
