This fan would be decent except for one thing: the pathetic control system. Aside from the intake/exhaust switches, there is only one button on the fan. Not a switch, a dial, or anything else but a lone button. One button to cycle through high/low, on/off, and the various temperature settings. Airflow is adequate and it is not terribly loud. Basically, this is a decent fan, but you can get a better one for less.
