Product review (4 stars): This is a great range hood.
I bought this to help increase ventilation in our 1,000 sq foot home, which is very tight. It works great! I love the lowest setting because I can barely hear it, but can see steam getting sucked in. The second setting is perfect for when we cook bacon, and the friend who installed this told us we may never want to use the third setting because it might create a backdraft on our boiler, it's so strong! The only reason I did not give it 5 stars is because I hear a very low buzzing from the fan when it's off. Like a ballast or something.
