Product review (2 stars): NOT A "FAN" OF THIS FAN!
My review is LOW due to the extreme, unbelievable, complex and poorly thought out assembly of this product.  A construction contractor for over 45 years, I know what I'm talking about, and assembling this device over a center-island buffet/oven range was a TOTAL FREAKING NIGHTMARE.  The instructions - sorry - were designed by pre-schoolers in their first drawing class.  NOTHING assembled as instructed; nothing assembled based on my 45+ years of building, electrical, roofing, venting, carpentry and finish work experience.  I was forced to modify the entire product to fit the space, which should not have been necessary; modifications included cutting stainless steel, drilling new mounting holes, modifying the inner-hood assembly to accept power connections, modifying the lower hood assembly to allow suspension from the upper hood mount.  From packaging removal (packaging was excellent, and in 2 boxes) to final assembly and test, this item took 4 days straight to "get right" because it was not manufactured in an installation-friendly way.  One wonders if the manufacturer even / ever assembled their own product, and if so, how they could be this incompetent.  HAVING SAID THIS...with the modifications I made the overhead unit is in place, looks fantastic thanks to my modifications, and works fine EXCEPT THAT the "dimmer light" do not work at all, they only work on one "bright" level.  What a disappointment, major delay to a kitchen remodeling project.  Great price - lower than Lowes by over $700 - but...I DO NOT recommend this product unless the manufacturer makes significant, clear, modifications to instructions, assembly, and installation procedures.  You will need to be Houdini the magician to install this if you are anything other than a very experienced construction contractor.
