Product review (5 stars): worth every penny
I used to heat my garage until I was able to put one of these in. the best thing...keeps working perfectly throughout the winter. my refrigerator would shut off (<3 years old) when it would get below 40 degrees in the garage. I had the unit checked because I couldn't understand why the fridge would defrost and not work. the repairman told me that the new fridges are like this...below 40 degrees and they shut off due to where the thermostat is placed (now in the refrigerator part, the old models had them mostly in the freezer).

this think works fantastic! works all year round, even when it's below zero outside
