I have this 30" Frigidaire cooktop for about a month. Is woeking perfect. I chose this model because the box under is a little smaller and it fit good into my old opening. For other 30" models I would have had to enlarge the opening on countertop. Also I like the control buttons on the side, rather than in front. Only thing different is that this has two medium coils and two large (one with small option), while my old GE had one small, two mediums and one large with small option. The wiring was easy. Have both options of power from wall black-red-ground, or black-red-white-ground. [This review was collected as part of a promotion.]
