They are beautiful right out of the box very light weight  sturdy. However they scratch easily we have used only silicone spatulas when cooking wthese  yet still there is scratching. Also the black paint or whatever it is on bottom of one of them where the black meets the silver cook induction plate is chipping. 
It’s actually an under statement when I tell you we have been careful w this set of pots  pans we have been EXTREMELY careful. We have only hand washed them, are careful while handling, our china dishes get treated more roughly. 
I dont know, like I said its a beautiful set just proceed wcaution.
