Product review (5 stars): Worked fine for me
It installed straightforwardly for me - and range hoods can be problematic for do it yourselfers.  It smoothly goes from a light quiet flow up to a great 440 CFM.  I love that high volume setting for keeping steam and scent from filling the house - it's very powerful, particularly for that price.  The higher the flow, though, the louder it gets.  And when cranked all the way up it is quite noisy.  It took awhile for me to get used to, though now it doesn't bother me.  Two drawbacks: the light is an odd size that I had to get online - even my Home Depot didn't carry it; the plastic knobs are very cheap and brittle.  Broan is happy to replace them for free, but I've gone through 3 in the first year.
