Circulon Ultimum Small Oven Tray 2 "May have been faulty" Mrs Doody 28 December 2020 At first I was very pleased with this oven tray. It was easy to clean and can be put in the dishwasher. However, after fairly light use, and almost a year, the surface coating began to bubble. Then the surface began to actually lift off revealing the bare metal underneath and the tray was no longer usable. A note from the team We're sorry the tray was faulty, I'm glad we were able to help you with a refund for this.
