Product review (4 stars): Great fan
If you lack vertical clearance, this is the fan for you. It's approx. 2 inches shorter (top-to-bottom) than the other styles. Pretty quiet on settings 1 and 2. Setting 3 is also fine and will evacuate most semi-normal steam/smoke - e.g. full boil on stockpot with no lid on front burner. When you get in over your head (oven rolling smoke), setting 4 is extremely powerful, but also somewhat noisy, although not as annoying as cheap fans. Our system is vented horizontally to the outside, so I can only speak for external venting (only way to go). It could stand to have separate buttons for each fan speed; the cycling feature is hokey. It's also somewhat lame not to be able to plug right into a makeup damper like some of the other styles; at this price I would expect such a feature. Overall I'd recommend this fan, esp. for tight vertical space locations.
