The reason that I did not give it five stars is because it seems kind of poorly designed. The power cord is connected to the main unit so when you extend it up to maximize height (which is why we bought it) it becomes an eyesore and inconvenience because the cord is dangling and shortened quite a lot. I used to own a fan many years ago with the same concept however the power cord was fed thru and came out the base much like a torchiere lamp. I prefer that greatly over this.

Pros: It cools very well
Cons: Powercord
