Unfortunately we only used it once before it stopped working.  There was supposedly a factory defect and it between filing the warranty claim, getting a repairman to look at it, ordering the part and replacing the part we were out of a cooktop for three weeks.  Only had it operational for 2 days so fingers crossed it will continue to work how it is supposed to.  Looking forward to induction cooking as this is our first experience.
