i like the way it works all in all but there is a big BUT 
i feel that no range hood should have no type of plastic moving parts that old the exhaust fan together, 
there is a plastic nut with a small metal thread that melted of because of the heat, that keeps the fan secured, luckily i was able to retrofit a metal nut to keep the fan moving 
and i also feel there should be some type of warning about what type of exposure or how much heat the hood can handle
