I ordered from Bitmine - received nothing, ordered from KNC - nothing. Ordered from HashCoins - waited for a long period, but finally received my order in full. And ordered again and more!
From my point of view - they had delays because of their ASIC supplier (all we know who it is), but they are shipping and people are receiving their orders. I've talked at least to 10 people who ordered from HashCoins and who has really received their equipment, so wtf you are talking about??! 

Guys, I think that every your negative post here makes me and others very risky to get anything more! As you all know the situation with 28-nm chips on the market (Bankruptcy, delays etc. even BatteryflyLabs and KNC, who not answering my emails)....Be polite and gentle and you'll get yours instead of nothing!

They are the only company who has support and still sending quality made miners. In comparing to other ASIC suppliers they do really care about their clients: when I've got serious problem it was pleasant for me to talk to CEO personally who solved my problem.
My opinion - you can trust them!
