Product review (5 stars): GREAT PRODUCT.  NOT EASY TO INSTALL
I love the cooktop.  It replaced an older versiion of the same model.  The only problem was getting someone to connect the ductwork.  I wired it myself.  Very simple, but it took two weeks to find someone in Stafford, VA area willing to make the ductwork connection, and when I did get someone to do it, it cost five times what it should have cost.l
