Product review (1 stars): Coating chips off easily.
I bought these because I thought they would be more resilient than the silver ones I have, since they claim to be porcelain.  I thought these would be like real porcelain and sturdy.  They are basically silver with a black coating.  When I opened the packaged the black coating was already peeling/chipping off.  I foresee these just becoming more and more chipped and unpleasant to look at.  Also, they don't fit the burners as snug as the current silver ones  I have.  They look exactly alike but for some reason they wobble.
