Query: Great Fan

This fan had everything i wanted, particularly, independent controls for each motor (in/out/both). I bought 2 of these, then came back and bought 2 more. The only thing that i would change is that the cord be a bit longer, and they be stackable. I currently have 2 stacked in my patio door, but they're unstable.
