I received this heater about a week ago and I'm so impressed with it! Not only is a nice looking heater but it's very efficient as well. I really like the automatic shut off in case it should be knocked over, it shuts itself off so it won't start a fire. I also like that you can choose between 750 watt setting to save on the power bill or the 1500 watt setting to quickly heat a room. The slim design is a real space saver, and this heater can be wall mounted or free standing on the easy rolling casters.This heater is completely silent, no fan, this is the first convection heater that I've ever owned. I'm so happy with this heater and I'd recommend it to friends and family.
