Product review (5 stars): Great Range insert.  Worked so well I did not smell the smoke of an unattended pan.  Highly recommended
This unit was used to replace an aging in cabinet unit.  It produces a moderate amount of noise in the kitchen ( much less than the units that vent into the kitchen), but is excellent at removing smoke and steam from the range area.  The vent worked so well that I left a pan of pasta on the stove cooking until the pan was glowing red and the pasta had turned to carbon residue.  I have no regrets with this purchase and I highly recommend it.
