This fan is wonderful! It’s scorching hot where I live in Cali and it always seems to be the hottest in my bedroom. I put this fan in my window and it gets my room so much cooler. I am actually able to sleep and relax comfortably now. It was pretty easy to install once I got the hang of fitting the foam pieces into the sides. They fell out a couple times at first but once I got it snug in the window the fan hasn’t budged. Highly recommend!
