Product review (5 stars): Very pleased and a great way to update your old unit.
I have an older home that has a Jenn Air stove. Having owned a Jenn Air gas stove in the past I loved it, however my new home has the electric stove. I hated using my stove due to the older cartridges that were with the unit. They did not function properly and made it just a pain to cook. I love to cook and again the old cartridges were a total pain. So with hesitation I purchased this cartridge and hoped for the best, I was shocked by how happy I am with this unit. Now I enjoy cooking again. One of the big problems with my older cartridges is a metal lip that runs around the edge of the cartridge which made large pots impossible to use, and it was a pain to keep clean as grease and debris were constantly in the lip I had to use a toothbrush at times to clean it so again it was just a huge pain. The older ones did not work well with my Le Creuset cookware. This cartridge has no lip and all of my very large pots fit perfectly.  Keep in mind this is RADIENT heat so it does heat a bit slower and gets cooler slower as well but over all not a very noticeable difference. The cartridges are a breeze to keep clean and look great. Eventually I will be remodeling my entire kitchen but since I found these cartridges I can wait on replacing my stove.
