Product review (5 stars): WORKS AS ADVERTISED!
I came down to choosing between this and the 900 cfm Golden Vantage.  After reading the most recent reviews on the Golden Vantage, I decided to pay a little extra and get the HVI certified Broan---I'm glad I did!  Very happy w/ this purchase.
It does what it's supposed to!  As soon as it was installed, we cooked curried beef---you wouldn't know if I didn't tell you!  No more greasy and smelly kitchen!  Even w/ (2) 90 degree turns in our pipes this thing works as advertised.  Also, very easy to control the fan and light settings---You have to READ THE MANUAL!
As far as installation, we asked our HVAC guy to install it, it took him and another person about 3 hours, including installation of ductwork.  If you already have an existing duct, the hood itself can be installed in an hour or less.
