Product review (5 stars): Excellent product!
Quite on low speed and it still sucks the hot air out.
My only complaint is with the online documentation from the factory.  I downloaded the install specs to get a head start on the install and found nothing that I need to buy for the hood.  The downloaded specs says it comes with a cord with plug to be plugged into a wall socket.  It arrived with a pigtail, 3 wires ready to attach a cord with plug.  Also it said it came with a round damper, it did not, had to purchase one.
I would recommend that if you choose to go with the rectangular damper purchase one.  The one supplied does not seal completely, big gaps around all sides.
What happened, the PDF online is out of date, the printed spec is of a later date.
