KnC's inability to tell a consistent story was one of the reasons I happily chose to not to business with them. They've clearly stated both before and after product production that it was a structured asic run, and their power results support it. Ultimately it doesn't matter if they used crackerjack boxes to make their masks, at the end what matters is the specs and they're a mixed story. I mean, sure, feel free to not care.  But a 2x increase in operating cost, and thermal load is not "a few watts", especially for those of us not interested in a high risk gamble involving mining for a few months and then throwing the hardware out.

By all means, be happy with their product— they shipped a working device to many people mostly on time, better than a lot of other vendors, and many of those customers will be happy enough with a product that goes to the landfill before the bitfury and bitmain devices. Though in terms of feature size I don't see a reason to brag about 28nm when it doesn't achieve substantially better hashrate per U or hashrate per watt even close to multiple competing 55nm designs.
