Product review (4 stars): Good enough
The unit is not perfect.

I'm almost through my first keg (got the unit about a month ago).  The thermostat is iffy at best.  I'm still tweaking mine to get it into the correct zone.

One note on the foamy beer a lot of folks are experiencing - in many cases this isn't a problem with the regulator or pressure.  Most likely what's happening is that your beer line isn't as cold as the beer itself so if you're first pulling beer off the keg it's going to go through that warm(er) line and cause it to foam up.

I did some reading online and this is an issue with pretty much all similar units, regardless of price.  There is no air circulation in these units, the keg is being cooled by a metal plate in the back of the unit. Because most of the beer line is going to be above that metal plate, it's not going to be getting cooled like the keg itself.  The only way to actually "fix" this problem so that your beer comes out with the correct amount of foam on every pour is to stick some sort of fan (a computer fan will work) in the unit which blows the cool air from the bottom of the unit (where your beer is coming from) towards the beer line.

If you don't want to get into trying to jimmy-rig a computer fan into the thing you can just pour out about a quarter cup into a separate glass than you're actually going to drink out of to get rid of the foam.  Once you've run that first quarter cup of foam out of the keg you should be getting a good pour because the beer from the keg itself will have cooled the line.

Overall this is a pretty good unit for the $350 + free shipping I paid for it.
