Product review (4 stars): Clears the smoke!!!
So far so good. Everything came as ordered, quite powerful and not as noisy as the previous Broan that was in place which was rated for 450 CFM. The Ancona at its highest setting is less noisy than the broan and does an excellent job clearing up the smoke. I used to have to turn on my whole house fan to help clear the air but not anymore.

Reason I gave  4 stars only was due to the fact that it was a beech installing this thing. Its definitely a 3 man man job, 2 to hold it in place and 1 to screw the vent to the cabinet.

They couldve made it easier by designing a hook and screw hole that allows one to drill the screws in half way into the cabinet, line the unit up with the screws and simply slide it forward to keep it in place so it doesnt fall while the screws are tighten one by one.

Other than that, the unit looks great and performs wonderfully. Oh BTW, the handles that attaches to the grates need to be threaded properly so the screws can go in all the way for a nice tight fit. I sent an email to Ancona and they're sending me replacement parts.
