The build quality is fantastic and the portability is incredible! We received the product fast and the setup was what I was concerned about but once I looked at the directions my mind was at ease! I had it up and running within 10 minutes! I cranked it up to the highest setting and my room was cooled within a minute or two! It blew so hard I had papers flying around lol absolutely incredible and this summer will be a breeze! By the way I am in Arizona so this is a must buy!
