Had to return heater. It wont meet my needs and it rattled like something came loose inside. It wasnt what I thought I was getting because of misleading advertising. None of the caution warnings on the heater are in the product pictures. The heater has to be kept 3 feet away, back, front  sides. So its not supposed to be up against a wall as indicated. Also its not clear if this heats 300 or 40 square feet, conflicting information in product listing. Feet are plastic and it tilts forward a little. There was a rattling noise in it when I unpacked it. Not happy I had to pay return shipping either.
