Don't take the chance, I've handed over 3.44BTC for 3 boards and got nothing, no communications, acknowledgements. It's basic theft, absolutely appalled by this.
Quite why the company doesn't have a Z rating in the trust worthiness guide is beyond me.
Currently seeking legal advice....
edit: perhaps not looking at -
https://bitcointalk.org/index.php?topic=462370.3720 it looks like VMC are going bust big style.
Dunno...
If it's any consolation, VMC is in the 'Bottom 3' (as opposed to the Top 3, I suppose).
LOL, I think Butterfly Labs is in a league of their own as far as the 'Z' rating, so I think they've got a ways to go.
Also, a lot of people had issues of one sort or another with Hashfast, so I can understand that one...
I do see this note on the Comments:
Offered and honoured refunds from the start. Clones now appearing, original chips not yet ready.If you feel that strongly about it, and can show Dogie proof that you've paid and gotten nothing from them, he may downgrade them to a C- or a D.
Just a thought.
