Query: Disappointing

This is a plastic cake pan. There are few instructions, but the ones that are sent clearly indicate that this pan cannot be returned and that the pan has limited use. I used the pan twice, cleaned gently with soap and water as instructed, and the pan began to crack. I could have purchased a more durable airplane mold for the same amount of money and recommend that others do just that.
