Product review (5 stars): Fits Perfectly.  Good Price.
Before now, somebody else replaced my Jenn-Air's burners with generic ones, and they don't sit right.

I'm glad to be able to restore my stove to new condition with these burners which have the triangle-shaped support which fits into the base perfectly for a nice level cooking surface.  Good price, compared with replacements from the dealer.  Very quick delivery, also.
