Product review (5 stars): Works well and looks AMAZING!!!
Excellent product after using for nearly a month.  I had someone else assemble & install but what an exceptional look and function.  This vents straight out the back wall, through louvred vents.  East to use, without instruction.  The LED lights give a high end look to any kitchen.  Fits a standard 30" wide opening, so you don't have to have a commercial size stove to have that same appearance.  Three fan speeds are sufficient.  East to clean, with a step ladder.  Just don't lean your hand on the stainless exhaust trunk when cleaning, as it may become damaged.  This goes with any brand 30" stainless stove, since there is no 'brand' stamped on the vent.  Works very well and looks amazing!  So far, I highly recommend.
