I love using these rings. I can actually get 3 eggs in the pan without them cooking together. Personally, I think this 3" size is a little small for pancakes but they also have a larger size that would probably work better for pancakes. The rings have a handle on them so that you can easily lift them out of the pan when you're ready to. They are made of silicone so they won't melt or get overly hot.

I received this item for free or at a discount for my honest review.
Have a great day!
