We don't run it all the time, just when we are there (or know that we will be back in a couple days). It is not a large fridge either. But yes, it is very efficient, and always amazed just how little flame it takes to keep everything cool, incl the freezer. When you put your hand over the little chimney, you can hardly feel any heat at all. My guess it that a propane fridge would probably cost less to operate than a normal home electric one (but I could be wrong).
