The pans from the Tefal Unlimited series last up to 6 times longer than the other pan series by Tefal, thanks to the titanium coating. You can use the Tefal Unlimited frying pan to prepare a piece of meat and the wok to prepare a healthy wok dish. The Thermo Spot turns red once the pan has reached the right temperature. That way, you'll always know when the pan is hot enough to start.
