Product review (1 stars): If you don't have at least a 9 ft. ceiling, stay away from this product.
With this hood, if you have an 8 ft. ceiling and a standard 36 inch island, the vent will be about 26 inches over the island.  Fine if your a short person, but if you are 6 ft tall, it will be a problem.  None of this is spelled out in the advertising or specs for the unit, so I found it out after receiving it.  Waste of my time.  The installation instructions are 3 pages of minimum detail so be aware that you won't find a lot of help there.  Overall, a very bad experience and I still don't have hood.
