Product review (1 stars): corrosion after less than a year
I bought these burner covers for a gift for someone last Christmas.  I really liked the simple design that added interest without adding color.  I was dismayed to learn that less than a year since she received them, they have begun to noticeably corrode both around the rim and within the design.  They have not been abused, put in the dishwasher, or subject to a lot of use.
