We purchased the Windmill AC for 2 reasons. One, the location where we needed it was right behind our livingroom couch and a traditional AC vents right at you but the WM AC vents upward. This worked perfectly, we could sit near it without it venting on our neck and heads.. Two, the unit was advertised as quiet, it was and that allowed us to enjoy being cool without a lot of fan noise. One additional benefit that we found was the unit cooled a larger space than we expected. Where we used to need 2 AC we only need the one WM now. 
We did have a technical issue crop up and the support for this problem was phenomenal. They were professional, timely and friendly. Couldn't ask for better.
