I don't know how well this item is supposed to work. It does ***NOT*** substitute an air conditioner. If you think the price of this unit is on the high end, just don't buy a fan. You'd be better off rubbing soda cans on your face than using this to aid in the cooling process and bankrupting yourself in the process. I don't have a lot of experiences buying fans, so hopefully next summer I can buy a more pricey one.
