Product review (5 stars): Very happy with this hood
I wanted a hood with a variable range fan and 2-3 levels of lighting (need lowest level for a nightlight).  This was the only hood that fit my requirements. The quality so far has been very good except that the plastic fan/light knobs fall apart after 2 years. You can purchase new ones from Broan or the recommendation I have is for you is to buy a small tube of 2 part plastic epoxy.  Remove the 2 plastic knobs that turn on the fan and light, mix a small amount of epoxy, and shove the epoxy inside the knobs (but NOT in the very center hole that accepts the metal shaft of the switch).  The epoxy will re-enforce the knobs and they may last a lifetime.
