Product review (3 stars): Bad News: unit quite 2 weeks after installation ....Good news:  Broan customer and tech support excellent
Relatively easy to install if you have done a range hood before.  REALLY helps to have a second person to hold the unit up under cabinet.

The big bummer was this unit quite 2 weeks after installation.  Brian tech & customer support 800-637-1453/ 800-558-171 are very nice, helpful and responsive.  It seems the unit needs either a new logic board and/or motor ..... wow.  2 weeks.

As an FYI, to increase the hood suction, cover the upper side vents that are in place to remove cooking fumes above the unit.

Finally, does not evacuate as strongly as I thought.  Not bad, but no hurricane.
