I am very disappointed with this pan set. I have the large pan uses about 2 months. After this short time the soil is already warped. In the two smaller pans, I have found that my induction cooker not or only recognizes the pans when I several times back and herschiebe and firmly press the pans on the hob. In my other pots I have absolutely no problems, so it can only be connected to these pans. I have since bought myself another pan, with which I am absolutely satisfied.
