Product review (2 stars): Disappointed
I installed this vent hood using a duct.  I didn't notice from the photo that there is a piece of plastic that covers the front vents when the hood is used with a duct.  The piece of plastic looked cheap and didn't fit tightly against the hood.  It also wouldn't stay level which added to the cheap look.  When the hood was turned on, air blew out around the plastic cover, right into my face.

I could also see the welds on the front of the hood.  The finish was more of a matte black instead of a more glossy black, so it didn't match my range at all.  I returned the hood.
