I can only give you my opinion but I think others here will agree. I frown on the Chineese stuff because can you really tell what piece of scrap it was made from, if so, what testing was done on the material before it was cast. What kind of impurities might still be present in the metal. China doesn't have the best record, take children's toys for example, how often do you hear of them having lead content? So why should their CI be any different?
