Product review (3 stars): This is a clear case of, you get what you pay for.
As a contractor, I've always preferred Air King products when available.
Although the fit and finish of this range hood is very good, the 24 gauge sheet metal is much to light-weight. So the least little warping of the unit during installation causes the fan blade to rub on the fan shroud. Thus making normally simple thirty minute job into a couple hour ordeal of tin-knocking and adjustments.
18 gauge stainless steel would have made this average product, into something excellent.
