Product review (1 stars): Defective manufacturing and can't be cleaned
We bought two sets -- the first one arrived without any defects, but the top inside edge of the ring came off with the wash cloth in a 2" long strip.  So we ordered a second set, thinking it was a simple one-time manufacturing defect.  The second set we ordered came with the same defect already in place, still in the box.  Both times it was on just one of the large drip pans.  We kept the two good large drip pans, and returned the two drip pans that were defective with the original order.  Within 2 more days, a large drip pan sloughed off the paint, in exactly the same spot.  On top of that, if anything drips on, and is not cleaned off immediately (stop cooking, remove the burner, clean the drip pan, then reassemble), it becomes baked on, and cannot be easily cleaned off with a nylon brush and warm, soapy water.  Their quality control manager and people need to be terminated, and the paint needs to be of a higher quality to make it a true ceramic, and not just an enamel paint.  It is a shame that an American company cannot put out the high quality that used to be the standard of the world.  I don't know what I have available as an alternative to this product, as I threw away the ugly shiny OEM silver drip pans which were no worse than these.
