Best slim, quiet and effective fan. The super slim design makes it a great space saver in smaller rooms. It has multiple settings that range from inaudible to a low hum, perfect for white noise and sleeping at night. It is a great buy, easy to use, and ready to go right out of the box. I highly recommend this fan and will be buying additional ones for our bedrooms. It works exceptionally well to keep indoor air circulated and creates a nice cooling breeze for comfort. We have been running it 24 hours a day since purchase.
