Product review (2 stars): It looks nice and it is easy to use but the fan ...
It looks nice and it is easy to use but the fan is situated on the left side of the unit and only is strong enough to affect the left side of the range top.  I cook mostly on the right side as that is where my large front burner is.  So in effect, it does nothing to pull the greasy steam into the unit.  We used the recirculating feature, or ductless and I don't know if that makes a difference as it is capable of being a ducted vent as well.  Overall, it is not worth the money.  I would make sure to use the paper test on both sides of the unit when looking for a strong recirculating vent. Now that I recall, the salesperson just did the paper test (to see if it will suck up the paper)on the side that she was standing, which was the left side where the fan unit is.  We just struggled to change a light bulb because the light socket was not anchored properly at installation.  Of course this was the bulb on the left side and was almost impossible to reach because the fan unit was on the left and not in the center.
