Product review (3 stars): Looks good, no draft.
My prior fan did not duct to the outside. If yours doesn't either be prepared for some significant work to get it installed and ducted.
Pros: It seems to do the job and remove smoke and odors. It looks nice once installed. it is not too loud. I wouldn't call it quiet either but it is ok. I was very concerned I could get a cold draft as this is on the north side of a house in Massachusetts and the winter wind hammers that side of the house. I used the Broan 641 wall cap and there is no draft.
Cons: The mounting screws I received were the wrong size. The metal is on the cheap / thin side. My old Broan hood was built with heavy gauge steel, this new one could be easily bent. Packaging was poor. Unit arrived with a couple of bent areas but fortunately they were on the back side and will not show once mounted. The center panel of the black plastic on the top section just snaps in. Mine came off during shipping.
Recommendation for Broan: Between the box and the cardboard inside the box there is an opportunity to make a mounting template as part of the packaging. Installation would be much faster if one could just hold up the template and trace the duct and screw locations. Fix the mounting screw issue and include more than 4. Add a timer so it could be set to run for  5 minutes or so then shut off on it's own.
