Well, the arbitrary claim that it produces a bottle of wine that is as good as a $20 bottle isn't wrong; however, that claim also isn't right either.
My point is that I've had some really crappy $20 bottles of wine, I've also had some really good $5 bottles of wine; "good wine" is very subjective.
This product is very similar to the soda stream; separate the ingredients, shrink it down to a smaller production size and claim it's an amazing innovation, when in reality, it's not.
As far as "cost savings" sure, this system may be cheaper than going out and buying a $20 bottle of wine a week for the rest of your life, however, most people that drink wine regularly do not buy a $20 bottle of wine a week.
Most people that make wine, already have their own equipment most likely won't be tempted enough to purchase this.
Basically this system incorporates a stir plate, oxygen stone, and heat source to speed up fermentation. I feel that anyone that makes yeast starters could assemble a similar system with what they have lying around the house, granted no bluetooth or smartphone connectivity.
I also think it's very pretentious to call it the "miracle machine" when there is nothing new (aside from the combination of existing technologies in a new way), let alone miraculous about it.
I'll stick to my 3/5/6 gallon batches that I can cellar; I've already got he equipment and honestly, they aren't all that expensive on a per bottle basis.
But that all stated, I still drive a car with a manual transmission, so I may just be an old foagey that resists change.
