10 Stars! I am in love with this pan! I have been using this pan daily since the day it arrived. I was so skeptical of "ScratchDefense". It has been years since I used a metal spatula. Well, I decided to give it the best test I could. I cooked crumbled sausage. Chopping it with a metal spatula, stirring it around, intentinally trying to scratch the pan. I figured if I ruined it, then it wasn't meant to be. IT LOOKS BRAND NEW! Not a single scratch in the pan! I am sold on this pan and it beats every pan I have owned and I'm mid 50's. 
Heat dispersed evenly on my gas stove. You can actually use lower heat for most things it heats so well.
I will be adding to this first pan and slowly start replacing my other pots and pans!
One more thing, do not fear the ridges in the pan. They didn't affect even a fried egg.
