Product review (4 stars): These work just fine.
I have had them before, but after 15 years decided to order a replacement set. The enamel gets grungy over time, especially if you are cooking anything acidic and it boils over. Given the fact that the stove is 40+ years, the sets are hard to come by, so I ordered two full sets, one for when the house is sold at some point in the future, and one for now. By the way, old or not, I will use the stove and double oven that goes with it until it stops, and I can't get parts. I like the double oven, and the stove works pretty well.
