Product review (4 stars): Broan 47
The hood came to me very slightly dented on the top, but not so much that I wanted to return it.  Previous reviewers mentioned excessive noise on high, and ease of assembly and installation.  Insofar as excessive noise when set on high--no.  The noise level is completely acceptable when set on high.  When set on low you can't even hear it.  The assembly though not a breeze, was fairly straight forward.  Don't try, however, to install by yourself as the size can be a bit unweildly.
