Product review (4 stars): Looks great but WEAR GLOVES
Looks great!  Has a larger chimney, which we needed to accommodate slightly off center ceiling vent access.  This was the third hood we ordered while trying to find one that would work for us.  I gave 4 stars as the directions are NOT very clear and could be written better.  While this states it can be installed/mounted directly into drywall it is definitely more secure with would supports added (if you don't have studs to mount to).  Wear gloves when installing the chimney.  The stainless steel edges of the chimney left numerous paper cut like cuts all over my fingers and if you have ever had a deep paper cut, they sting and are painful.  All of that said, if I had to purchase another range hood, I would not hesitate to go with Cavaliere and buy this one again!
