Description of product on amazon did not mention that grill could not be used on flat top stove. Directions on box mention this so buyer is unaware until delivery.
I was really excited to get this for my husband, so that he would stop being so down about not having an outdoor grill (we live in a condo). We tried it the first night to cook burgers and after 10 minutes, took them off the grill and into a pan to cook. Might be good for vegetables or really thin pieces of meat. Plus, there is no cover. We are returning this item. Don't buy if you want to cook meat with this.
Bought this as a gift for Christmas, my friend asked for this but says its worth more trouble than anything!
Answer: Place it so the curve is up. It should make a bump not a dip.
