Product review (5 stars): Very good product.
I ordered this with the hope that it would override a refridgerator's thermostat, so that I could use it to hang prosciuttos and salamis for curing. The intent was to get the fridge's temp into the mid-fifties range. It works very well in doing so, keeping the temp range between 54 to 58 degrees. It is easy to install and set the temp to what one would like, with only a little bit of experimenting with the controls.
