I received the 2 pack of frying pans, one large and one smaller, and I was skeptical at first.  They have the rings, or grooves, that circle the pans.  I thought they would be harder to use.  I thought the ridge would make it more difficult to get the spatula under my grilled cheese or eggs.  However, I didn't encounter that issue. Something makes it easier for things to lift off. The pans were really easy to clean with just soap and water and a light scrub.  To put them to the test I used a metal whisk to make sauce.  I've posted the photos, too!
