We bought one last year for $400 and put it in our coldest room - a 16 x 16 with a 7 foot ceiling and I could not tell that it anything to heat that room - tried it for a few days and took it back. Our local electric co. has a newsletter that comes out once a month and they talked about those heaters (not by name though) and said to save your money and go buy a $40 unit at WalMart/Lowe's and it has the same wattage and will do the same job for the same money - just spot heating.
