Product review (5 stars): Great for converting old freezers into lagering fridges.
I used this to convert an old chest freezer into a lagering / cold crashing box.  It was VERY simple to hook up.  I ran the temperature probe in between the lid seal and plugged the freezer into the box, and the control box into the wall.  I set the freezers temperature to max and then adjusted the temperature dial to the temperature that I desired.  I added a thermometer inside of the freezer to see how accurate the control box and probe are.  It's within a degree or two, so I am happy with it.  Saved me hundreds on not having to purchase a new fridge for my beer.
