Product review (3 stars): It's not a Whirlpool.
It's ok.  I had to replace my Whirlpool hood due to a small fire that emanated from a pot of hot oil.  Anyway, I have Whirlpool gold appliances throughout the kitchen so I wanted to ensure there was a match and purchased this instead of a Broan which looked much like the original I had.  This looks nothing like the old one but what's even more interesting is that it's being sold as a "Whirlpool" but no where, I mean NO WHERE does it say Whirlpool on the unit.  Not on the front, not on the back, not underneath.  Makes me suspicious.
I'm very aware that Whirlpool most likely does not actually manufacturer the hood.  Same goes for the oven, microwave, dishwasher and refrigerator.  However, all those appliances say "Whirlpool" right on the front.
