Product review (5 stars): This Range Hood is well worth it.
The shipping on this product was very good.  As soon as got the range hood I plug it in and tested before installing.  It worked and surprising it was quite at it highest speed.  Installing it was a little complicated only because my house did not have duct work.  The vendor Golden Vantage have pre-package an 8" duct that did not work for me.  I had to make several trips to Home Depot just get the right ducts.  I'm still not completely finish and missing 6" duct that connect from the range hood to the duct outside but the range hood is installed underneath my cabinet and I have to say that it look really good and works amazing.

On the side note - It took me a really long time to install by myself.  You definitely need two people to install this range hood only because it heavy and needed another pair of eyes.  Overall, it's a great product.
