Despite delay in production process I must recommend marto74. I have ordered several units. All of them are of excellent quality, and fully working. Also contact was very good all the time (PM/mail response in max 24h).
Units came safely packaged with security tape all around the box. All of them exceed promised hashrate by +8-12%.
I am sure I will place another order.
Luck for you...
I'm still waiting for an order, payed on 2013-10-03, marked as shipped since 2013-11-01.
When i asked where is my board, he answered (by pm, 2013-11-18) that the data about my order have not been updated by the carrier.
And since this, no answer to any of my message, private or public. I have not receveid the "newsletter". I have no board and no news.
So maybe some are happy with technobit products, as for me i'm really upset about the technobit communication.
