We currently own (2) Dyson and they are awesome. They also chill the air that circulate through them by about 15 degrees We've had them for 2 years now and wouldn't trade them for anything else they are worth every penny
I have a Dyson Air Multiplier, and I love it. It throws out a large amount of air movement, and you can feel it pretty far away. Plus, it is something everyone loves when they see it.
Every time I see the commercial, I think I might want to see about one, but I assumed they were probably pretty pricey. I'll have to see if my local Bed Bath & Beyond has them.
