I have owned Corelle French White bakeware for more than a decade. I loved it, so when my daughter asked for a set for Christmas, I was happy to get a set for her. I find the quality is not what it once was. I prefer the flat bottom on my set over the raised ring under the new set. The lids on my older set fit beautifully. The lids on the new set should have better quality control. In addition, I ordered 2 replacement 1.5 quart bakeware dishes to replace those broken at Thanksgiving. I had to order the lids separately, which would be fine except that these don't even fit as well as those in the 12 piece set that included lids which also don't fit well. I am greatly disappointed in Corelle's French White Bakeware now and will think twice about ordering from Corelle again.
