This replaced a similar unit purchased over 20 years ago. It is basically the same item but with some updated dials and trim. Given my good luck with the other one I declined the extended warranty as Maine, by law, requires manufactures a much long warranty than they offer. I am very pleased with the unit; it works great, has the features I need and it goes well with other appliances with stainless steel trim, etc.
I love this cooktop! When we moved into our current house, the cooktop that was here cracked after using it twice (it was fairly old). We replaced it with this one. That was 5 years ago. The only reason we had to replace it again was because I dropped a giant glass measuring cup on the corner of it and it shattered. Totally my fault! I liked it so much we replaced it with the exact same one. It's very easy to use and keep clean.
