Conclusion: Kids got this for there mother for Christmas. It replaced a whirlpool gold cooktop that was 14 years old always worked like it should. Had to replace broken glass top on it years ago from a dropped mayo glass jar. The new one was a little larger so had to cut granite top to make it work.
Summary: I have had several issues with repair services for other appliances purchased with Sears two years ago but despite that purchased a new electric cooktop from them. I like this cooktops simple design, easy installation and reasonable price. Let's just hope nothing goes wrong with it.
Summary: Would have given a 5 star but after first use defects in glass top on burners showed. Called Whirlpool they said its normal can't be fixed. Not happy with that answer. Can't recommend this product. Usually love Whirlpool appliances.
