Product review (4 stars): Fine looking - very difficult install - poor instructions.
Product is fine, problem is the design of the install mechanism - at least for my planned install.  I did a ventless install under a soffit using only one of the chimney pieces = the one with the slots.  Difficulty is that the hood essentially hangs from a bar but to place hood on the bar it must be raised one inch to clear the bar before setting it down on the bar.  Well that one inch throws off the chimney install - now it is no longer flush with the ceiling.  After many tries got the install done.  Be prepared for a difficult install for those with my specific install requirements.  The instructions are completely worthless.
