Black Arrow is a scam company and stole millions from investors. Do not do business with them. There also is no confirmed X1.5 units that have shipped yet, since they were supposed to be for compensation and BA reneged on sending any compensation to those who got screwed by them.
I was lucky and scored 2x X1.5 units with power cord, wifi antenna, screens for $80.
Theyre a hell of a lot nicer to play around with and the power consumption alongside
my single Rockminer New-Rbox is a hell of a lot more enticing than my first miner
which was a bulky, power hungry monster Antminer S-1.
Oh they also came with the original invoice and ship date which was in June-2015.
You actually got an X1.5? I'd like to see it, never seen any evidence of them shipping anything other than the X1's
