The fan heater does what it should: it heats a medium sized room very quickly in stage II (1500 watts) and then maintains the selected temperature due to thermostat (intermediate shutdown when the temperature has been reached). In Stage I (700 watts), however, is only a gentle breeze, this step seems only suitable to maintain a low temperature difference on a pleasant level. Otherwise, makes the fan while it heats, of course, a lot of noise; for classification: two current PCs (about three years old) he has drowned playing. But you can definitely still entertain. ;) The safety shutdown functions reliably as long as the level surface is flat. Penetrante smells I could not find a moderate plastic smell is gone after a short time.
