I will never forget the summer of 1986, wife pregnant and the central air zonked out. I ran to the nearest large store to grab a fan and actually i was going to grab any fan. I was walking down the fan isle when i noticed 3 to 4 people grouped in front of this small looking yet powerful fan. They were laughing and feeling good. It obviously made everyone cooler. I noted the blades were quite different allowing them to circulate air at a awsome speed. The output shocked and amazed me. I got lucky and grabbed the last one and headed home. Please don't take my word for it just go see a demo. Mine is still working great to this day. My son Peter enjoys it as much as we do! This fan is a winner in all ways. Thanks for listening to Bill
