Product review (5 stars): Kegerator Converstion to a Kezzer
Since chest freezer dials only allow for temperatures of freezing and below.  I had no way of keeping my kegs cold enough to where I like my beer (40-45degrees). I decided to try this device out and it has been outstanding. To limit the frequency of which it turns on, you can  placed the thermometer in a glass/bottle of water. That way, when the liquid gets to cold, that's when the thermostat kicks in and turns the freezer back on until the liquid is at the desired temp. Also saves the compressor so it's not kicking on as much.
