Product review (1 stars): Many Experiments - still foamy beer
I have owned this kegerator for 3 months and still have foamy beer. There is a great post about 10 different items to try. Super helpful. I have been going through each one and have done several experiments to reduce or eliminate the amount of foam with limited success.

First thing was that the thermostat at the coldest only got the temp down to 42 degrees. I followed some helpful YouTube advise and now it fluctuates between 32-36 degrees. Additionally I added some water bottles in there to minimize the how much it fluctuated.

Next I have been experimenting with the pressure. Even with lowering it down to 7-8 psi, I still get 3 inches of head on each bear I pour - even when I pour consecutive beers. I no longer pour into a pint glass - i only use the super large/tall glasses - otherwise half my beer is foam.

A minor adjustment that was very helpful was wrapping the hose on top of the keg. It is very important not to let the line dip below the top of the keg... another source of foam - or so I have been told.

At this point, I am considering taking the connections all apart and starting from scratch. I have gone through 3 pony kegs and the best solution I have come up with is pouring into a growler first. Be careful when purchasing this product - you may have to work on it a awhile before you get a good glass of beer from it.

UPDATE - 8 months after purchasing: Extreme temperature variation without opening the door - ranges from 27 degrees to 44 degrees.
