I have owned many different “non-stick” pans over the years; however, most turned out to be “non-non-stick”. For the ultimate test, I made simple eggs over easy. Imagine my surprise when, without grease, butter, or oil, these eggs didn’t stick AT ALL! Turned out perfectly. That is a rarity. Then, I cooked salmon with the skin, and guess what? No. It did NOT stick. And clean up was too easy. I actually felt like I missed out on the exercise of scrubbing the pans clean. 
I am sold. Should the time come, I only hope I can replace them with these exact pans.
