I recent this stove less than 48 hrs ago. I used the air fryer, loved it. I used the Cooktop to heat soup, wiped the condensation off before after removing the pot and the  ultra heat burner is missing the black coating down to the silver. I'm disgusted and so disappointed. We have waited for this stove to be available, ordered in December 2020. My old drive could be cleaned without a problem. I'm at a loss for words at this point.
