I can see this in a commercial setting, but any family/household that wants to drop $600+ dollars on a folding appliance, may be better served with a $30+ / week maid, who also does the folding. How does one justify $600+ on saving 16 min a day? How does one sell this to any consumer with a >$100,000 income to a household?
