The Profile has the ability to sync the two left-hand elements but its elements are smaller (largest: 9", 8"). The Kitchenaid's two largest elements are 10". Home Depot owners seem to like the Kitchenaid better.

IKEA is selling its FÖRVÄLLA and NEDDRAGEN radiant cooktops -- yes, they have knobs -- with 9" elements for a remarkable $500 and $430, respectively.

I expect most buyers are purchasing induction cooktops such as the Frigidaire Professional FPIC3077RF instead of radiant models.
