Product review (4 stars): Kind of pricey for what you get.
I have been camping in near zero weather this winter and this kit is what I needed to keep my frig working. I had to remove the mounting screws and slide the refrigerator out about 6-8 inches so I could get my hands up to the coil to clean and mount the heat element. Instructions were a little hard to understand at first, however after reading them several times it went well. It would have been easier to remove the frig from the cabinet completely but I did not have the help. It was kind of pricey for what you get in the kit, however it did seem to work well in ambient weather down to 5 deg f on this last trip.
