Wish there were more videos than these 15, 30 or 60 second clips. I could not find one installation demonstration - not from Windmill company itself nor from an individual youtube presentation. All of these videos make it seem like the air conditioner leaves the box and magically floats into the window. I was considering the Windmill and the Midea. With the Midea, there is ample installation information, actual step by step demos by real people on real windows. I am reluctant now to even consider the Windmill Air since I haven't even seen anyone touch it let along do an actual installation. I'm surprised that the Windmill company itself has not made such a video.
