Product review (1 stars): Would not recommend
Would not recommend.  We bought this when it first came out several years ago and worked well initially and then about 2 years later, we started to smell smoke and cooktop no longer worked.  Turns out the casing around the circuit board had melted.  Very disappointed as we had bought 4 Thermador appliances for our kitchen renovation 6 years ago and since then 3 (out of 4!) of the appliances have malfunctioned/broken completely (always right after the warranty runs out).  Thought we were paying extra for quality and reputation, but sadly that does not seem to be the case.
