I'm not crazy about the efficiency. It's great for a 28nm miner, but doesn't really compete with the current 16nm gear. But I believe we have to support smaller manufacturers, or we are going to get stuck with more of the same from Bitmain. I am willing to buy and run one of these, even if I only break even on it. Though with my power rates it should ROI in less than 5 months.
Where are you hosting at where you can get ROI in under 5 months and still has capacity?
