I was excited to get this, it is the end of summer and here in fresno where we live, can be the hottest month of the year. This window fan is lightweight and small but works so good. It cools amazingly well. And the best part is that it is so dang quiet. When my husband put it up in the window for me when I was at work, I came into my bedroom and it was fresh in there. He said "how do you like your cooler" I could not hear it at all. First fan I have ever owned that was so quiet. Keeps us cool at night.
