Cooktop, was designed poorly, not easy to clean around burners since the a actual burners do not remove. The ceramic top leaves streaks no matter how much you try to buff using the cleaner that was sent with it. I would not ever buy this again! The cast iron grates are beautiful however they just sit on the ceramic top and if are not on perfectly the flame sputters and the downdraft  rubber seal is going to be a nightmare to clean when it is older. Not to mention it doesn't fit properly under the downdraft grate. Whoever designed this cooktop apparently does not cook on a daily basis or if does does not do the cleanup!
