Product review (4 stars): Great range hood
We purchased the Broan QS330SS range hood because of it was provided the most air flow among the hoods within this price range. Assembling the unit was very easy but I found some issues:
1. The power cable is not supplied.
2. Mounting hardware is not supplied.
3. The top cover of the hood is flimsy and hood is supported from it.
3. The flapper did not have enough space to open, so it had to be removed.

The hood was mounted to vent through the top. The unit is very silent and powerful. I am amazed by the amount of air that it is moving. The control buttons are a bit ackward but we got used to them very quickly. Overall, we are very happy with this hood.
