Stainless steel is in good order. I use it on an induction plate: it is as fast as a kettle, or even more. The look is appealing. Only "small" flat, during boiling, it hisses, but the whistle quickly jumps under the effect of pressure! careful to orient it on your plate to avoid the risk of accident or burning, especially with children! it is a product that I recommend, very good price / quality!
