For 15+ I had a Vornado Model 280ss and never had an issue with it. I decided to upgrade to the Silver Swan Alchemy thinking I would get the same build quality I have come to expect from Vornado. This has been one of the most frustrating fans I've ever purchased - on low speeds the fan rattles and I can't get it to silently operate aside from the fan moving the air. Don't get me wrong, I love the vintage look of this fan, but if you're looking for something practical and effective, get another model.
