Product review (5 stars): Does what I need it to do
This thermostat control is very easy to use.  You just plug your refridgeration device of choice in -- I am using a small wine refrigerator that I am using for aging hard cheese that I make -- and set the desired temp on the dial.  I have a digital thermometer monitoring the temp inside, and the temp stays just where I want it, within 3 degrees of the set temp.  This control unit seemed to have the best price point when I was looking for this product.
