I have been in contact with skyfromwell and seeksilence for a few weeks now.
They have been very evasive on disclosing chips, pcb, and now even an evaluation unit. Every single time a question came up...they have been very evasive.
And those answers actually led to more questions.
Here is my take:
From the sounds of it and the 1 on 1 dialogue with skyfromwell and seeksilence on QQ.
They probably have stolen or infringed on the Bitmine 28nm chip IP. The demo unit they told me they would send 7 days ago has not arrived. They came back and asked for $6000 USD.
If I am to be a distributor of their product I am not dropping $6000 on a unit that is worth $3000.
I work in the chip packaging industry as well...stuff like stealing chip IP happens a lot in China.
While, I do not doubt they do have a working miner, I would advise great caution until a trusted Bitcointalk member can verify they are running an entirely legitimate business.
Very Respectfully,
