Product review (4 stars): Looks nice installed- nothing really jazzy
Received this hood several weeks ago, but just installed it this week.  Ordering and shipping was a breeze.  Arrived without any scratches, dents, or anything broken.  Looks nice installed- nothing really jazzy, but nice.
I know when I ordered it that I really should have a 600 CFM hood, but anything over 400 CFM requires (or may require) a special makeup air unit.  We are selling the house and it will be inspected, so I knew it needed to meet code, and so I went with just 400 CFM.
We mounted it at 30' (they tell you to mount between 24 and 32 inches above your range).  Anything lower would have meant hitting our heads if we had something on the back burner.  By the way, in most ads or on HGTV, they generally show the hood mounted way higher than it should be for effective performance.
Although the vent tests at 400+ CFM with a meter held directly under the fan, the smoke and or steam is drawn up, but then kind of drifts toward the front of the unit.
It still is better than the old vent we had, and while it may not suck all the smoke and steam as you are cooking, it does get it out pretty quickly.  No more bacon smell throughout the whole house.  :)
My opinion is this: if you are going to keep your house a long time, buy the proper amount of CFM for your range (or maybe even extra) and spend the extra money to get makeup air properly calibrated.  I think it would be worth it.
