I bought this range hood about four weeks ago, it is awesome! Works great and has many useful things like the timed turn-off, the reminder to clean the filters, and the dimming lights with last setting memory. This is the only range hood with 900 CFM under $500 on the market. Installation was simple, and the assembly of the chimney duct was also a breeze. I recommend using rigid metal ducting if you are routing the duct through the roof. I would of like a longer factory warranty though...
