Great video! I bought two I'm fixing to buy another one. They weren't available in the store but I bought them online for $44.99 and they were worth every penny! This is an incredible powerful fan!
The device turns off after only 4 hours, which is not enough for my need of using it throughout the night for sleeping. As a result, I will be returning it.
Mine runs every night when it is hot, all night long, until I turn it off. Just don't use the timer buttons, they are just a feature, you don't HAVE to use it! o.O
