We are sorry for this experience, Ash. We have some important tips for you to protect this aluminum set. 1) Always use on low to medium heat. 2) Always cool down to room temperature before washing. 3) Avoid sudden temperature change (thermal shock) on the cookware and lids. 4) Avoid sharp adjectives touch on the cookware surface. Please know the set can be returned for a full refund anytime with the Member's Mark 100% Satisfaction Guarantee.

Our cookware is equipped with a stainless steel stay-flat base specifically designed for use with induction cooking surfaces. Please ensure the diameter of the pan’s induction base is equal to or larger than the size of the induction element being used. If the pan’s induction base is significantly smaller than the induction heating element, the induction sensor might not recognize the pan and therefore not activate the heat evenly.
