Product review (3 stars): Works, but needs a better beer selection, and a bit overpriced IMO.
This does what it say it can.  It can keep a (pre chilled) 5l keg cold and dispense it.  The complexities of a tap are replaced by a pinch hose.  If you buy the deluxe you can use non pressurized kegs.  But even in a big city like Houston, its hard to find the kegs and its even harder to find good beer in them. EdgeStar has to help push brewers to adopt these.  If they do they'll sell more, if not, this product will die off.

I bought mine for homebrew, and I expect it will do fine.  I'm replacing the CO2 cartridge system with either a paintball setup or a 5lb CO2 bottle:  getting those threadless cartridges to seal properly is a pain, and you loose a lot of CO2 that way.

I think it needs better insulation.  The Peltier struggles to keep the keg cold.  I have modified mine for better sealing of the door and insulation, and this has improved things.

If we do a part breakdown, we have:
1 peltier and coldplate, big heatsink and fan
plastic shell and insulation
very simple digital thermostat with temp probe
plastic pinch valve
associated plumbing (all plastic)
CO2 regulator/Gauge

Looking at it from this perspective, I don't think the price is warranted.
