I have two other fans...NEITHER of which even when combined has 1/100 the effectiveness of this small but powerful fan. I just bought this a few days ago and LOVE IT!!! It moves the air, cools the room AND me better on low than my other fans do on high! It does exactly what the description says it does. However, unless you experience it for yourself...you can't possibly understand how wonderful it is have such a fan. My apartment is hot all the time and the other fans weren't effective unless they were on high which meant a constant roaring noise over which I could not hear the TV or have a phone conversation. I can position my new Vornado, turn it on low, easily hear over it and be very very comfortably cool. Thanks to Vornado...my life got better. I plan on checking out their other products.
