Look, I'm NOT a salesman, but my wife & I have used these little heaters in our small rooms and our overall electric bill dropped by over 30% a few years ago. I did a lot of research on them and overall most was positive. The negative was when using them not in accordance with mfg recommendations. Just thought I'd pass it along if anyone has small rooms in their house and wants a very inexpensive way to heat it. I hooked up a $5 thermostat from Grover's and it works perfect. Anyway, for what it's worth. http://www.eheat.com/
