Product review (2 stars): Too hard to install
This would be a fine range hood for the money, but it was almost impossible to install.  I couldn't for the life of me figure out how to modify the baffle for the 7" round vent, and eventually gave up and used a piece of black duct tape instead.  Not ideal, but at least it works now.  What should have been a simple install was turned into a circus.  I also noticed it is really quiet at the lowest setting, sure, but at that setting nothing much gets vented.  On the other hand, the higher setting, though much louder, pulls plenty of air.  If you're planning on having a professional install this unit, which is what I ended up doing, go for it.  Otherwise, find another range hood.
