I just received my 783DC ENERGY SMART Air Circulator, this afternoon… I was hesitant to spend so much on a floor fan, as I am on a limited income; this is no floor fan!  Air Circulator IS the correct terminology!  Talk about QUALITY!  This is really built well!  I decided to make this purchase because of the propulsion design and the Energy Smart, DC technology.  I live in an Electric Co-op area; electricity is VERY expensive!  I do not have A/C, either…  This really moves the air, and is so well built I don’t think it will ever wear out.  I was so tired of horrible, breakdown fans… now I have comfort, at last…  I will save up to buy a second 784 DC ENERGY SMART AIR CIRCULATOR for my bedroom.  (I will never buy anything else, again!)
