Thank you for the great rating and feedback, Chi. As a reminder, we do not recommend using metal utensils that can damage or scratch the surface. Also, please store your cookware carefully, avoiding direct contact with metal or sharp objects.

We are sorry you are unhappy with the cooker, mustang. Please know you can exchange or return it anytime as part of the Member's Mark 100% Satisfaction Guarantee. Here are the important tips for you to protect this pan. 1) Always cook on low to medium heat. 2) Always cool down to room temperature before washing. 3) Hand washing recommended although dishwasher safe. 4) Avoid sudden temperature change ( Thermal Shock ) on the pan and lid. 5) When using gas, keep the open fire just touching the bottom of the pan and avoid the open fire climbing onto the cooker walls.

Thank you for the great rating and feedback, Stacey!
