Product review (3 stars): MIRROR FINISH PROBLEMS X3
Love the look, cooking performance and clean up but I have just had to place another call with Thermador for another replacement of the glass cooktop. I haven't even lived in this house for a year. This was purchased brand new. They are having a production problem in China with the mirror finish. The mirror finish starts turning into black spots that grow like bacteria and get bigger. Think of a antique mirror and how the silver starts chipping away.
