Product review (5 stars): I thought it was quite easy with a little planning and ingenuity
I don't know what all the fuss is about with installing this unit.  I read several reviews before purchasing and saw quite a few saying it's difficult and do not attempt on your own.  I thought it was quite easy with a little planning and
ingenuity.  Here's a tip for the do it yourselfers out there.  Spend $10 and build yourself a support to set it on when mounting it to the ceiling.  I know it's only eight screws but you'll thank me later.  I built a wooden support structure out of lumber about 1/4" below the mounting height and used bar coasters to shim it the rest of the way up.  It still takes two people but it made it a breeze.  Only took about ten minutes to build the support too.
  As for the hood vent itself.  The lights are adaquate and the suction is very good.  It actually makes the flames on my gas cooktop dance when I turn it on.  It is a bit noisy on high but that's what happens when you move air rapidly.  It looks very nice and modern.  Great addition to the kitchen.
