This is a top-of-the-line model that can also rotate in reverse. It can be used year-round, for diffusing air during winter heating or as a fan in summer. I installed it and used it a few times, but I've been busy, so I haven't used it much. I think it's in beautiful condition. It's easy to use, blends well with the room, and I recommend it.
