Product review (5 stars): I would rate this 10 stars if I could.
I am only just getting to this review because I wanted to "kick the tires", so my apologies.  During kitchen renovation, I refused to settle for another over the stove microwave vent that just blew grease around my kitchen.  I wanted something that would be attractive, functional, easy to clean, and flexible enough to install in a 100+ year old house.  I researched many, many models for months before deciding on this vent and it's worked out to be everything I had hoped for.  Not only does it look nice, the exhaust is fantastic - minimal stray grease above those grills, which actually come out easily and clean up wonderfully in the dishwasher.  I had questions and contacted customer service who responded quickly and thoroughly every time. We had to retrofit this in a space that was shorter than is usually required and I needed spec sheets, among other concerns (would ventilation  be affected if I cut it, etc). The vent and chimney also clean up with dish soap and this cost at least $1000 less than other chimney vents.
