Product review (3 stars): Could be better.
This fan is a lot noisier than the older model I replaced it with.  The actual fan is left of center so if you have smoke rising from the far right burners its not going to be as efficient.  I don't know why the manufacturers did this but I was very disappointed when I did some post installation smoke clearance testing.  If you require a round damper you'll need to order it separately. It only comes with a rectangular damper.  The installation directions are confusing and very difficult to understand.  The on/off buttons for the fan and light do not work as efficiently as my old model.  The two light bulbs are not included.
