Cute heater, but unfortunately there is a very strong chemical odor emitted when the unit is running, with the heater on, or with only the "flame" light on. The size is just right for a small room & the "flames" are pretty & relaxing, until your eyes start to water and the dry hacking cough starts up. I was hoping the smell would go away, but it has been 5 1/2 weeks & the odor is just as strong as it was on first use. Beware!
