I bought this in July and should have returned it but I thought LG was a reputable company that would honor their product.  The front corners on the cooktop are "wrinkled" and they won't admit it's a design defect.  Hope they have this in their kitchen!  I put a dent in the stainless strip by just bumping a pan on it.  Didn't try to lie about it.  That is all the tech had to see to say he would not replace the cooktop.....the elements are also not right....he tried a test but he is aware of the issue and knew how to get around it.  The technician was kind enough to take a key out of his pocket and stuff the oven gasket back into the hole that it should have been securely fitted into.
