The range hood is great!  It looks awesome and works flawlessly.  It is a bit tough to mount perfectly because you can't fully tighten the hood to the wall because then you won't be able to slide the chimney cover over the back lip.  I love the look and quality of the baffles vs the mesh filter others have.  Another tip is to get some stainless steel cleaner/conditioner so that finger prints don't show up.  After I put the weiman stainless steel cleaner on it, man now it really shines! The included ductwork is plastic, which seems fine to me and makes installation easier, I just had to buy a 3 dollar part to make it fit our old rectangular duct. On the whole, I'm super happy with this purchase
