This fan has served me well for over a year now. It has very impressive airflow. Even better is the small size of the fan. Mostly I use the fan to circulate air in my bedroom, but I have also used it to move cold air up stairs and hot down. It works very well, you will be impressed! I did have to take the fan apart and re apply oil once after leaving it on for a month straight (voiding the warranty, haha), but it has been working great ever since the reapplication of oil. It also provides a nice soothing hum for people who like a bit of white noise when they sleep.
