Product review (5 stars): The install is not easy unless you have access to previously established duct work
I saved some cash purchasing new in box via on line auction...Then had my contractor do the install for $350.  The install is not easy unless you have access to previously established duct work.  The install needs to be correct otherwise what you will end up with is greasy air being circulated though out the interior walls of your house = mold.  I mention the cost of the install only to highlight it took a professional carpenter most of the day to complete the job.  The duct work done goes above the kitchen cabinets and vents out of the soffit.  Anyway, this range hood is awesome!  The lighting is perfect, fan is whisper quiet on low. On high the blower is super powerful, loud, but will clear any residue of cooking out in 10 minutes.  There is also an extra feature to the fan, click the time delay and it runs for a few minutes and shuts off automatically...handy for entertaining.
