Normally I am not one to think anything about a fan, but after I purchased the Vornado, i realized that not all fans are the same. The Vornado fan is like the BMW to cars, high quality and high performance. With its 5 speed dial, this fan can push air 100 feet without even sounding like it is trying; I have to occasionaly check to make sure no one turned it off because I can barely hear it. I am the type of person where I will keep my fan until I have to clean it, and this fan has never failed me; it is constantly running without any problems. Its grill is shaped to help the flow of air to maximize the effect of the blades (which are also designed to push the maximum amount of air for its size). The Vornado is a one piece fan, there is no dials or knobs to tighten to swivel or change the pitch of the fan; its structure allows for three positions: 0Ëš, 45Ëš, and 90Ëš with respect to the ground. This fan is useful in any large rooms such as a master bedroom, living room, garage, or anywhere that needs to cool down.
