We do not understand the good reviews for this product. The coating is absolutely inferior. We have now tried 3 copies of this pan and all had to not even send it to a year ago, because the coating is totally scratched, or dissolves (lift with your fingernail).
We have never overheated - we never fry sharply. In addition, only wooden utensils used and washed by hand. The last attempt of the red dot caught in the middle after 6 using detach itself. After 3 attempts we believe in no production error more!
