The Windmill AC is a beautiful and easy-to-use product. They've considered every detail when designing this product, from the unboxing experience to the hardware itself. The materials feel high-quality and durable, which is important for a piece of equipment that runs daily such as an air conditioner. My only complaint was that I did not realize there were two different iOS apps based on when the AC was made, so that caused some confusion when I tried to connect the AC to wifi. Otherwise, it is a fantastic product that performs well.
