wo...actually i don't have any comment as they claim to be the official...as all here selling the miners "unofficially" and even many non-official reseller have good sales and reputation (i want to be one of them too )

what i believe is if you can provide competitive price together with good service you will get the customers.

but what can confirm now is scrypt-hash they are really "EX official", hope "diginforce" really the diginforce i think..

um. scrypt-hash now just like everyone here..
