It gets really hot at this time of year, and I bought this fan to complete the a / c, while I must not crank it up so high. Its quiet enough that I can leave it all the time, but it provides enough air to keep me scrambling for control of a / c. The USB cord is also nice, because I do not have to run another cable on my wall. For that price, I'll probably buy a couple more for the other rooms of the house.
