Product review (5 stars): I was extremely pleased with the amount of air this fan moved as ...
I am in the process of installing the unit now.  Looking forward to it being in.  I Have plugged the pre-wired unit into the wall to get a feel for the air flow it will put out and how quiet it will run.  Comparing it to the previous under-cabinet, ducted unit I installed years ago, I was extremely pleased with the amount of air this fan moved as well as how quiet (to me) it was on each setting.  The overall construction of the fan housing is sturdy.  The finish on it is very nice.  The double fan housing itself is impressive.  Everything on the unit looks to be well thought out and nothing seems to be cheaply made.  My only issue, and I just realized it two days ago, is that one of the two "clasping side springs" (part number B02011013) and its corresponding screw is missing.  These clips hold the unit in place inside whatever housing you use.  I need to obtain one of these springs from Broan so that I can install my fan now that I am to that point.
