This Product is beyond efficient. My expectations for it were exceeded. Initially, when I saw the size, I was a bit discouraged and was expecting something bigger, but to my greatest surprise, the heater worked better than I could have hoped for. The 2000watts setting is so extreme, it makes me feel confident for the coming winter. I have recommended it to 2 friends already, although one stubbornly got theirs from the store. I'm hoping the other would get it from eBay too
