Product review (5 stars): Looks great & works well!!! Love it
Put in a remodeled kitchen last year.  Works very well!  Neighbors must be delighted to not hear our smoke detector going off every time we use the oven/stovetop!  Two settings for the fans that are vented to the outside of our house.  The lower one is not very loud, but the higher setting is quite loud!  Not a bother to us, as I feel that we know it's working well when you hear the fan blowing.  Easy to clean & love how it looks!!! Our contractor stated it was easy to install.  Highly recommended.
