These deteriorate very rapidly if you have them close to a high BTU burner. I have a Kitchen Aid stovetop, the largest burner is 14,000 BTU, and these lose their shape and turn into goo within 2 weeks. Yup, I used high temp black silicone to secure these. I've bought 2 different sets of these from an appliance parts co. and had the same problem. Figured I'd try the Bosch and Viking grate feet from Amazon -- the Viking feet failed as well. Frustrated!
