I had to have my mother's fifty-year-old stovetop replaced. Purchased one online, not knowing it was an induction cooktop. That meant my mother couldn't use many of her pots and pans because they were non-ferrous. Replaced the cooktop with the Cosmo model. Radiant heat, and knobs instead of push controls. Much more like what she's used to, and easier to see where the burners are located. Very satisfied
