Product review (5 stars): Best vent ever.
This is the best vent I have ever owned.  Completely removes cooking odors.  Even the tough ones like cabbage, greens, fried shrimp, bacon.  Yes, it is a bit noisy, but it's a good tradeoff for the work it does.  I have yet to need to run it at its highest speed.  I installed it myself and I'm only an intermediate level DIYer.
