I purchased this to replace a different MinkaAire fan that for some reason made a continual gawdawful humming noise.  Fortunately, Build returned that one with no issue and I replaced it with this one.  I'm very happy, while simple in looks, it's quiet and puts out a great deal of air if needed, but we mostly keep it on the 3 setting and that's enough.  It's a DC fan so I understand that's energy efficient.
