I have email logs of them refusing to give me a proper update status on the "updated" 2TH machines and am willing to post them. With full confidence that this company would live up to their expectations and be the first US based company to actually deliver on promises I made a pre order on an April batch miner before the first one ever delivered.  (big mistake). 
       After seeing initial numbers I gave them the benefit of the doubt that they would have it fixed.  They said they were working on it and through a string of correspondence, they kept me from pulling the trigger on a refund with promises that they were working on it, and it would be ready by my april batch (have email proof of that too).  Well long story short, April first came around and they already had posted an update regarding their crap pci-e mining card and still had no update on the  new board design. On that day (April 1) i asked for a refund.  Low and behold, April 2 rolls around and they update their website with obvious bad news for april batch guys such as myself.  Someone from there emailed me a couple days later asking if i wanted to reconsider my refund now that they updated their website to which i replied NO. 

      I refrained from saying anything about their company because I wanted to wait the full 4 weeks they said it would take to get a refund.  (Funny they took my bank wire instantly).  Now that the 4 weeks have passed, i've been emailing them every day asking about the status of my refund to which now i'm being ignored.  I will update this thread daily for those waiting on Cointerra refunds that may be in the same boat as I am, as well as give insight to any potential customers, if they even have any of those left.
