I purchased this item after reading all of the positive reviews on it over more expensive models and I have been very pleased with the results!  I am able to keep the thermostat on 65 for the house and use this on 70 in my bedroom at night. It keeps the room warm thru the night and I have high ceilings in that room too.  I only hope when I get my next electric bill it isn't a trade off in fuel savings only to double the electric bill! I love the feature of it being on wheels, as I roll it into the large bathroom half an hour before I shower to heat up that room too.
