First video review I've seen and its great. You folks with video cameras buying here please get them out and make a short video like this on products you purchase where sound especially is a factor as seeing and *hearing* the device is worth the proverbial thousand words! Thanks Prof!! It would be too loud for me to sleep with so you would have saved me the disappointment and bother of having to return it if I were considering it for that rather than as a bathroom heater. Even there I think it would be irritating as I'm noise sensitive.
