In use for 9 months.   Is been a great cooktop and love the amount of cooking area for a 30".   Only complaint is that little rubber feet on the bottom of the 3 grilles (4 each) can fall off.  If you don't notice and put the grills back on with a missing rubber foot, the grill will scratch the stainless.  Frigidaire should include extra feet with the grilles, or improve the design.
