Product review (4 stars): it's adequate.
I ordered this particular hood after reading that it was quiet. Not really.  It is no quieter than the cheap builders' hood that it replaced, and a lot more expensive.  It is also far larger than I expected- sticks out further into the room than my previous hood.
On the positive side, it draws air very, very well.  It has two lights, not just one, making it easier to see your work surface.
