I bought a new Maytag glass top not long ago. I was promised by the store rep the top would not turn black on the burner circles. After a while the circles turned black and looked awful. I took a picture and showed Sears. I was told So What, it still cooks fine. Not our problem. I contacted Maytag and got the same response. I didn't buy the stove to look ugly after use. Maytag and Sears lost a customer who changes out appliances often.
