I ordered Black Arrow X-3 on December 17 and paid $6,100 at the time which included shipping and wire transfer fees.  X-3 called for a Feb shipping for 2 TH/s. 

We all know what happened to that date.  They weren't even close.  The missed it by such a big mile that it's obvious they were never going to make that date.  The reason given to us was that the power that the early unit was drawing was 1.5W per GH/s and that was going to be uncompetitive.  Seriously?!  The only competitor at the time was the AntMiner S1 and it was drawing 2W per GH/s.  They could have shipped the X-3 in Feb and we would have all been thrilled.  And they would have had extra months to get X-3A out with a better power draw.

So, now we are mid-May with a promise that one day we'll get a 3 TH/s for the cost of an additional power supply.  I ordered the power supply about 2 weeks ago from MineSource for an additional $255 putting the entire cost about $6,400 for 3TH/s with no idea when I'd get it.

YESTERDAY, I decided to also order 2 units of Spondoolies SP-10 with a promised hash rate of 3TH/s.  I reached out to Guy Corem, the CEO of Spondoolies who offered me a deal to purchase 2 SP-10's for $6,000 including shipping.  I paid something like 13.5 BTC ... and to my surprise, I already got a DHL tracking number for my order!  GREAT WORK, Spondoolies -- wow, what a great company.

So, I'm out $6,400 with BA since December for a 3TH/s product with an unknown ship date and another $6,000 for 3TH/s which I paid yesterday and will receive in the next couple of days.

I am not asking for a BA refund because I really want to know how this story turns out.  Even if I get a better deal from BA, I'm not even sure I'll have enough electricity to run it.

BA -- please take some lessons from your competition.  Spondoolies rock!
