Query: Works well

I had no problems using these for fried eggs in a skillet. Remember that the cooking surface should be flat as rounded bottoms will cause leaking. I also greased the ring it self with a small amount of country crock on my fingers before cooking. The eggs slid out easily. The kids and wife were impressed and my 3 year old squealed with delight.
