Product review (4 stars): Quiet, pretty but dented
After reading reviews I was very leary about purchasing this due to the numerous scratch and dent comments.  My hood arrived a day early which was awesome.  The box was in perfect shape and I was very hopeful that I would have no scratch/dent issues.  I unpacked the box with the aid of a helper so all the pieces were removed carefully.  Everything looked great on initial inspection and all the stainless surfaces were covered with sticky plastic wrap.  Laid everything out in prep and read through instructions before beginning.  The instructions are extremely vague.  A simple image of screws going up into the ceiling through the bracket not noting what screws to use (although there are only 4 screws large enough).  Also it comes with wall anchors but I can't figure out why because there is no way it would support the weight on anchors alone.  I had my vent, electric and blocking on the inside of the ceiling ready to go however the blocking didn't line up with the bracket.  I installed the provided screws, two of which into a stud, two into the provided anchors because I was just missing the stud.  As soon as I allowed the weight of the hood to pull on the screws the two in the anchors began to pull out from the ceiling.  Those two screws had to be replaced with the metal anchors that butterfly open after up inside the ceiling to provide the proper amount of strength.  Back to the instructions... it basically says "install the bracket and installed the supports" but doesn't elaborate.  So with a little bit of DIY experience or common sense you can figure it out but the instructions really stink.

The plastic vent pipe provided that connects the fan to the existing vent pipe is too large to snugly fit the top of their own hood.  The instruction photo vaguely shows what looks like a hose clamp on the vent connecting to the hood however there was not one provided.  So I installed it and used duct tape to seal the pipe to the hood.

After everything else was completed I began to pull the sticky plastic off (since I wanted that on until the last second so I wouldn't scratch the stainless) and I noticed about 4-5 dents/dings on each side of the square shrouding.  Upon review of how the item was packed, I am certain that the dents came from the metal bracket pieces that are wrapped in foam and tape and just dropped into the cavity of the shroud during shipping so it allows the metal bracket to rattle around inside and dent the shroud from the inside out.  After all of this work I am debating on if I have the energy to take it all back down to return it.  I am going to first attempt to deal with the manufacturer and see if they will send a new dented piece.

The fan is ALOT quieter then I expected.  Some people complained about it being loud but I did not find that to be the case.  If you know the sound  that an over-the-range microwave hood fan makes you will think this is 50% quieter.  I am extremely pleased with the look and operation, just disappointed it was dented and that the instructions leave a lot to be desired.
