Product review (4 stars): Fits Older SCE and SVE models
The older Jenn-Air radiant models have a trim piece around the edge that prevents pots larger than about 9" from seating on the radiant surface.  This unit, designed for the newer modular Jenn-Airs eliminates that edge, which makes it much friendlier for using larger stock pots, pressure cookers, and Dutch ovens.  Although Jenn-Air does not mention this, it is backwards compatible with the older units, and blends in just fine with the design of the older units.  It is very expensive however, which is why the 4 star rating.
