I am interested in this primarily as it would be a good way to make a small batch for trialing a new beer that I may not want to dedicate 3-4 hours for the brewing and cleaning aspects of my traditional setup.
You can remove the wort after it is cooled and ferment in another location. So like any of these other devices you will have your system locked up for 4-6 hours during the active brewing stages. I believe that's why you can buy it with various quantities of minikegs.
It has a current cheaper price than the picobrew, doesn't require proprietary brewing packs, has the capability to have completely controlled fermentation, hyped up app, and dispense beer if your willing to tie up the machine that long. I am more worried about, "if it sounds too good to be true...."
