DO NOT PURCHASE WITHOUT BUYING THE EXTENDED WARRANTY! 
I purchased this cooktop in late 2021  for $2,500.00 and it has stopped working all together. Called Samsung repair and the service tech who came out said it would cost over $2,000.00 to repair. They would have to remove and completely dismantle the cooktop to replace all (4) of the circuit boards inside. It is likely that in a couple of years the same error code would appear and the cooktop would stop working.
