Product review (4 stars): Great Hood, but loud!
Hood is well made and therefore quite heavy.  It is noisy at the lowest setting: at full speed, it sounds like a jet taking off!  We thought the food would be sucked off the range!

The keyhole mounting plates are not stud spaced (i.e. 16"), so the wall will need reinforcing behind the dry wall.  It cannot be mounted using drywall fixtures since it is too heavy.

Also, at 760 CFM, you will need to install some form of makeup air system (most state building codes require make-up air for any hood over 400 CFM).  The reason is simple: if you are moving 760 CFM of air from inside the kitchen, then the same volume of air must enter the kitchen from somewhere!  In our case, the cost of the external vent and automated makeup air system linked to our heating/AC air ducting was over $1000!  The instructions do not mention anything about makeup air (and according to our installer, no manufacture really deals with this issue).
