We live in a really hot climate and don't have equal air circulation because of vaulted ceilings in our home. We have been looking into trying a window fan and am so glad we were able to! The fan fits our window well. It blows in cool air and helps to make our room cooler. I really appreciate that it is not a super noisy fan! It seems well made and like it will last a long time. I'm considering getting another one for another room in our home. I can see this unit saving us some money each month by reducing the air-conditioning usage in our home. I highly recommend this product!
