I have a Beertender at home. It’s great… if you like foamy beer. The CO2 is built into the kegs you purchase (which are limited to Heineken, Heineken Light, and Newcastle). You get a decent pour about halfway through the keg, but the beginning and end push out about 80% foam. Which is terrible. It takes about six minutes for the head to settle before you can fill that gap with half beer/half foam. So expect to pour three times per glass to manage the head.
It works better if you pour into a pitcher, but why would you want a draft at home if you’re going to just put it into a pitcher?
