Product review (5 stars): Can't beat the price!
This one replaced an 20 year old Rangaire.  The Broan definitely isn't a heavy, sturdy model, but really do you need a heavy duty fan?  Grease is bad for you.  Fan appears to be very strong so far.  Adjustable?  Not really necessary since you are either gonna fry heavy or just cook some regular stuff like eggs.  I had to replace the old ducting used by the old Rangair ducting was caked with grease.  Note that the fan has both the round and square baffels so you don't have to run to Home Depot and buy them.  This fan is light and easy to put up by yourself, however I recommend getting your significant other to help.  I agree with others the Range hood has that expensive stainless look so it's a great by in the 42" range.  So far so good.  I'm a happy camper.
