Product review (4 stars): Good range hood insert and low noise levels.
We've only had this unit for a month but so far it has exceeded my expectations.  The sound levels are much less than what I expected.  The unit installs rather easily into the mating Broan liner.  However, I wish that the cover would be able to fit a little more securely (other than the two black tabs) to fit more snugly to the unit.  I've only ever had the standard Broan units before this one and this is leaps and bounds above that unit.  It would be nice if it came with LED lights but they are an easy upgrade nowadays.  Installing incandescent candelabra bulbs are just too dim to be useful.
