Product review (5 stars): Reliable, durable and easy to use
I have two of these. One of them is about 15 years old and still works like a champ. I originally bought it for use in converting an old fridge to do lagering for beer making. I now use them to control the temperature of my dry curing cabinet. They are very solidly built and a piece of cake to use. Just plug the freezer into the controller's plug, them plug the controller into the wall. You can use a couple of screws to mount the controller to the freezer (I recommend the door so you don't puncture a coolant line).
