Query: so called "cast iron" wok

I ordered this wok thinking it was cast iron and similar to products in cast iron from Creuset, Lodge, Wm. Sonoma. I got a wafer thin steel wok that has been spun to look like cast iron and it has two handles welded onto it. It was coated with a blackening of some sort that rubs off on your hand revealing the shining bright steel beneath it. My wife refused to use it as she was worried about what was coming off of it. So, it sits unused. I then ordered a cast iron BBQ wok online from Target and it is exactly as advertised. True cast iron, nice and heavy and useable on BBQ grill or burner. The wok tool and ring from Wok Shop were ok. In general, a waste of money.
