Product review (5 stars): This Controller Works!
This item works perfectly for my 'cheese cave' fridge. It was very simple to install and took about 2 days to get the temperature where I needed it. The one problem I had was my fault: I installed a remote temperature sensor which gave me false highs. Once I removed that and installed a refrigerator thermometer with an external dial I could see that the controller works to within three degrees of the desired temp.
