I planned on buying the 12" Thermalon Rocks pan. It didn't have a lid, and one wasn't available as a separate purchase. I got this one instead. Am I glad I did! This pan is a good weight, isn't flimsy in any way. The rivets are tight, The lid is very good quality. I've used it several times now and have had absolutely no problems with sticking. I always add just a smidge of olive oil before I cook, but I did that with Teflon too. IMO a Teflon coating can't begin to compare with this. I made a panful of scrambled eggs with cheese a couple of nights ago. Nothing stuck, not even a crumb.
I normally don't recommend things to friends, but I've told everyone I know about this pan. I feel safe in doing so because I have a friend who has had the original enamal set for over a year. She uses the 8" fry pan every morning and told me a couple of weeks ago that the non-stick works as well as it did the day it was new.
