I know I found it very valuable!
BTW, when I asked All-Clad about their core thicknesses in their fully-clad lines, they told me that was not available to consumers. ... What a joke.
In the end, I went back to my favorite ...nonstick cookware. However for SS, in my humble opinion, you can't beat the Emerilware SS line. It has the best copper base core & All-Clad's lifetime warranty.
I had reviewed the following lines before making my choice: All-Clad, Emerilware, Calphalon (all lines), Kitchen Aid, Cuisinart, ScanPan, Sitram, ... & more I don't remember now.
