Ive had this for a few months now and I am in love. Ive owned several window fans but this is the sleekest, quietest one. However, the internal temperature sensor is not accurate in gauging the room's temperature. I wish the unit was smart plug compatible so I could pair it with a smart wall outlet and my own smart thermometer. This would allow me to create smart routines based on the outside or inside air temperature or time of day, very handy for when I am not home. This is easiest with analog switches and buttons but I've had lamps with capacitive buttons that were capable of this too. Additionally, the ability to adjust the angle of the air a bit would be nice. In spite of these shortcomings, I am very satisfied with the fan.
