Product review (5 stars): After playing around with placement of the copper probe and figuring out good temperature this device is working great
My husband and I purchased this to convert a stand up freezer into a beer fridge, for our regular fridge space was diminishing daily.  After playing around with placement of the copper probe and figuring out good temperature this device is working great!  We still have to see if it stands the test of time, but so far so good.
