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.
You can watch and compare testing performance of Gen3 M-Cycle dew-point window air conditioner side by side with legacy brand. At comparable retail price (with enormous potential of M-Cycle for scale effect reduction) our Gen3 demonstrates EER 80+ and 20 Watt electricity consumption (with EER 11.4 and 400 W by legacy brand). ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d8B_GNt-hH8.html
