Product review (5 stars): Great hood
This is a great hood. Installation was just 2 screws for the main body; and 2 near the ceiling for the exhaust cover. No need for a manual. But you will need to do your 6" ductwork, which is a task. After a lot of research, this seemed to be a good value. The big box arrive so promptly.

The hood is attractive, gets compliments form family and friends, and very easy to use. The three speeds correspond to: Q = barely noticeable, and easy to have a conversation; M = noticeable, but not intolerable, ok for talking, good for routine cooking; H = loud and also pulls a LOT of air, ok for smokey cooking.

One criticism: I don't love the LED lights which are too focused on the front, and the light color quality is not the best (compared to an incandescent/halogen).
