Great product! We’ve had them for awhile and they still don’t stick, but we love they don’t have all the chemicals of traditional “no stick” pots and pans. Like any pots and pans, they do begin sticking if you aren’t attentive to the heat. (I did this with one pan when I got distracted while cooking and it’s not ruined any any means, but it definitely sticks more now that I let it overheat.) Great alternative to less healthy options.
