We love, love, love this fan. We've had other portable fans before, but we like this one better! It has three speeds, is quiet, lightweight, and does a great job of moving air. We love the shape and the work. We love the look and since we've got it we've been finding more and more ways to use it. It runs on both battery and AC power. We think we'll end up buying a few more because we really like it and want to use it in a lot of places.
