Product review (1 stars): Do not buy, totally ineffective.
Loud on setting 2, really loud on 3! Smoke pulls through lights instead of carbon filter and grill, making the carbon filters pointless and in effective, making the door control of this unit non-existent. Left light is loose and wobbles on and off. What am i gunna do, uninstall the whole damn thing and exchange it for another one that'll probably do the same thing? Broan should uninstall unit and install a new one. Thing is pointless. Broan now has my information and complaint. If they wanted to fix this issue, they'd email me.
