I was very excited when I purchased these heart shaped egg rings to fry scrambled eggs and make my breakfast sandwiches, a la EggMcMuffins.Instead, I was very disappointed by this product. The hinge at the bottom of the heart leaks. Fast. It does not form a sufficient barrier to get the eggs to cook. Instead the eggs poor through the tiny opening by the hinge like a river flowing through a busted dam.I have not tried it with pancakes however.I highly recommend you look elsewhere if you are cooking eggs though.
