Product review (3 stars): recommend for ceilings LESS than 9 ft.
Really wish the chimney had more "wiggle" room for 9' ceilings.  The chimney are in two 15 7/8 in pieces.  I would have loved the chimney pieces  to be about half an inch taller for an additional one in total.  The current setup has my chimney just ONE inch short of to the ceiling.  The hood is 12 1/2 inches and attaches to the wall via two screws that are 1 1/2 inch ABOVE the hood (total 14 inches; however the 1 1/2 inch does get covered by the chimney.  .  The instructions shows minimum height is 28 in and the max height is 36 in.  I ended up ordering the chimney extension for 10 ft ceilings.

Pros:
The fan is quieter than others (better than average).
The halogens are bright enough to light up the entire cooktop
Baffles DO NOT rattle ;-)

Cons:
No adjustments to the lights - they are just on/off
Chimney pieces have a lot of play for any ceilings less than 9 ft
Have to purchase the extension to fit JUST RIGHT.
