I also find these cheap types of woks to be very dangerous to use, irrespective of coating. I bought one from Debenhams online and had I been in the shop I wouldn't have bothered - the handle seems to weigh more than the wok, making it very unbalanced and unstable. In fact, it tipped when I was using it and like an idiot I grabbed it and burnt my fingers

I binned it and have a very heavy Tefal one now, with a non-stick finish that looks nothing like the photo above.
