I have a smooth top range that has enamal edges. On two different occassions I have dropped a LIGHT ceramic salt shaker on the edge and chunks of the enamal have chipped out. I was told this is not covered under warranty because its considered "use and wear"! Tell me why the enamal on a stove top range that gets heavy pots and pans used on it EVERY day cannot hold up to something as light as a salt shaker being dropped on it??? I have purchased the 7 and the last of my Whirlpool appliance!
