My son likes egg mcmuffin style eggs, probably like you or anyone else considering buying or reviewing this. Problem is that the ring is very flimsy - not in a cheap way, rather in a soft, light and amazingly flexible way. So when you plop it in the frying pan, it doesn't have enough weight of its own to keep the egg from oozing out from underneath. Plus, the diameter is a little large - it's literally the size of an english muffin, or larger. So the eggs are flatter and less eye appealing as a result.
Bottom line is that if you want nice friend McDonald's style eggs, you need one of these rings that has a little more weight to it to keep the wet egg from lifting it up and oozing out into your frying pan. I also bought the RSVP Egg Ring, Set of 4 and really like the metal one a lot better.
For the record, I ALSO bought the Norpro 994C Silicone Egg Pancake Ring Round, Blue and it's virtually identical to this one. I'm betting that they would make nice silver dollar pancakes, but not fried eggs.
