I truly love using my frittata pan!  Making frittata's are never easier using this well made pan!!  The frittata slides off the pan with easy and no sticky clean up.  This has made my life easier than transferring the egg mixture to a plate then in turn flipping it over to cook the other side.  Some thirty years doing that routine, so Merry Christmas to me and to my sister in law who I purchased one for Christmas because she also makes many frittatas. I love the interlocking hinges for added security when flipping so there are no sliding of pans every which way!!  I definitely would recommend this product over others any day of the week!
