Product review (3 stars): noise is an issue
the fan is very noisy...and i'm not entirely sure how well it gathers the air.  I can usually see smoke/steam, hitting the vents and then drifting over the front away from the unit.
So, back to the noise.  Its loud.  there are 3 settings.  setting 1 is loud...and 2 louder and so on.
I only have non exhaust range hoods to compare to, so this whole review could be moot.
There is also a constant buzzing that comes from the unit, when not in use.  clearly something is running and not energy efficient.
its nice, well made and looks great in our kitchen....but I wouldn't buy again.
