Product review (5 stars): "this is a great vent". I did not need the liner
This was a HUGE find!  All the vents I looked out were outrageously priced.  I found this on Amazon, was a bit skeptical until my builder installed it and said, "this is a great vent".  I did not need the liner, so I sent that back, you can't see if you put this up under, so no need for the liner.  The fan is very quiet, and the light is great.  Even on the highest fan speed, its very quiet and keeps my stove area vented really well.
