I think it's more than a scam.
I actually think they have a few real working products, but think about it: Why whould you ship a 150$ product to a customer (who's already paid months ago for the device), when you can keep it for yourself and have it mining for months at a few thousands dollars, just by saying: "The product isn't ready yet, be patient" ?

Anyone who's ordered will NEVER see their ASIC, and if some do, It will be because it is not profitable anymore.
