This fan worked out well. All I did was have to plug it and and turn on. Simple and effective fan.
I didn't even turn this fan on to try, after I saw that cord attached in the center of the box, behind the motor. This "feature" will allow putting fan in the window in only one way. I would understand if the fan had reverse speeds, but it doesn't. Also speed control is behind the motor too, so depending of the flow direction, one may need to reach behind the fan to control speed. Returned the fan right away. Old designs where cord and controls were on the side of the box, were much more ergonomic.
This is a great fan and it works great; no complaints...
¿I am in the process of buying several more of these box fans both for myself and for family and friends?
