Product review (5 stars): Strong exhaust, quiet, well engineered.
Solid product, very well made and works great.  Looked at other reviews and decided to get this one amongst several others.  No regrets.  Well designed hood, dimensions are accurate and structure is sound and well engineered.  Works beautifully, clears out the smoke/air over all four of my burners compared to microwave exhaust combo that it replaced.  Very quiet across settings; I mainly use the lowest as it works really well already, but sound is just slightly above whisper quiet.  Installation is straightforward but unit is heavy and ideally requires two people to install.
