Worked so well I bought a second one

Our upstairs bedrooms are always very hot in the summer and the AC can't keep up. I bought one of these to try and it worked so well in that bedroom that I just bought a second one for the other bedroom I haven't tried it with the heat in the winter but so far with a hot Midwest summer, they are working great.

It actually works! My office is always hot, even when the rest of the house is freezing. This actually pulls in the cold air, and makes my office the same temperature as everywhere else.
