Product review (4 stars): Decent
My previous house had the right floor plan, ceilings, and cabinets to allow for a really nice venting hood.  I was able to cook whatever I wanted and not smell up the house.  With my current home, I'm not so lucky, but I do have externally venting ducts.  This hood was the only one that I could find that would fit my space and provide the CFM that I wanted.  Long story short, it isn't as good as the "regular profile" hood that I had before, but it works decently well, and is better than any venting microwave I've seen.  It keeps a majority of the smells outside of my house when cooking, even bacon.  I would buy it again.

Installation was not difficult, but I don't think that they provided the best set of tools (no template), and it was defintely a two person job.  My biggest complaint about installation is that it only comes with the transition for 14" ducting, and I have 10" ducting.  I had to buy an overpriced transition in order to install it.  Ideally, Broan would have shipped it with the 10" transition so that it would work with the most homes, and force you to buy the 14" transition if you have those ducts and want less resistance.  Moral of the story is know what size ducting you have, and buy any needed transition before you get ready to install it!
