Very interesting piece to read about their thought process - and a very interesting product that I had not heard about before. If I was in the US, I would buy it. If they get international shipping (EU) at say an extra 10 bucks and no return shipping, I would still consider it, but I fear the cost of shipping + added turnaround time would make it a much less attractive value proposition.
