I was amazed of the air flow that was going through the garage. You could feel it all a crossed it from side to side. It brings cooler air into a stuffy and hot garage making it much more bearable to work in on weekends which is when I tinker around out there. I also smoke in the garage and it has helped get the smoke out of it. It is a great product and I am happy to refer any one who has a garage to get one.
