Product review (5 stars): Updated!
I purchased this to replace an old hood that did not match the kitchen and probably dated from the 1970's.  I am very happy with this unit.  It does not extend as far out from the cabinet as the old on, it uses a regular bulb (I use a compact fluorescent), and the filter screen is smaller. The filter screen is washable.
This model can be adjusted to use with or without external exhaust.
The fan on low is very quiet; on high it is loud.  I imagine that in most instances the low setting will be fine.
All in all I am quiet satisfied.
