Product review (4 stars): works well
This was bought as a replacement for the original broiler pan and rack that came with my built in ovens.  The design is nearly the same, though the original sets were not porcelain.  So far, the new sets have worked about the same as the original sets in cooking, but appear to be a little easier to clean, for now.  A previous porcelain rack that I purchased was easy to clean in the beginning but became more difficult in time.  I am hoping the same does not happen with these new ones.  So far so good.
