Product review (5 stars): This SUCKER works well.
Very nice hood.  I was expecting it to be louder based on the reviews.  It's not loud at all, even on high.  Much quieter than the unit we replaced, and this new one does about 4 times as much airflow.  Don't settle for low flow hoods....you're running an exhaust fan for a reason.  The LED lights are nice.  I wanted LED as the halogen type lights get too hot.  Instructions still say the lights are halogen, but they are not.  They just didn't update the instruction book for that little change.  The unit is heavy.  55lbs. shipping weight.  Make sure you're bolting into some solid wood.  Get a friend or spouse to help you install.  Installation was easy, and matched up to our existing rectangular hole straight out the back.  Has option to vent up, too.  Very solid unit.  Thick metal.  Not cheap.  Metal fan blades, too.  100% quality made.
