I have the wok now used about 5 times, I was at first very satisfied, but now is in spite hand rinsing and no metallic kitchen helpers the coating already defective. And of Tefal I got on the phone said I could send him back, but he probably would have been overheated that passing quickly when you step with the highest of working oven! ???? Because he is suitable for the oven to 260 degrees, I have not see that coming. He does not fit the way, but the stem is too long. (I have a normal 60's oven)
