Product review (4 stars): and definitely look much better than the old crusty original cartridges
These work well in our 30 year old Jenn-Air, and definitely look much better than the old crusty original cartridges.
They maybe seem like they don't get quite as hot (read: boil water as quickly) as the original burners, but they look much better.
Installation was super simple and we had no problems with fit or compatibility.
