Absolutely negative review because these are NOT non-stick whatsoever compared to Copper chef. Also a very serious problem with the Pan handles get very very hot unless you use  a hot pad or mitten. My wife burnt her hand first time using them pan searing veggies and eggs. Never had that problem with any other Brand EVER. !!  We pan seared some fresh shrimp and they got stuck to the pan immediately.
We purchased this set because of the  fancy advertising but take our word for it , it is not worth the potential for serious burns.
After reading the enclosed pamphlet ,it says  “ DO NOT USE OLIVE OIL “ this was never mentioned anywhere before purchase, only once you’ve shelled out the  will you find out. If you use olive oil it will ruin the pans !!! 
Who in the world does not use olive oil  
Very disappointed about the purchase of this set. Do not buy
