I have been using these for a few months now. They looks great generally, but started to scratch from the bottom only after a couple of weeks of cooking. Absolutely disappointed, because as a family we take our health seriously, so I took the responsibility to research and find a decent set of cookware set. Now I am going to throw them away knowing the health implications of bits of coating and chemicals in our organs exposing us the risk of cancer way outweighs the financial loss! Unfortunately, this has been a big let down and so regret paying so much!! we followed the instructions provided to the tea, so please stay aways from throwing your money on these cheaply made products with false claims or rather not well researched. Please know that I am not damaging anyone's business, but people's health shouldn't be compromised at all cost! Thank you
