Writing in the Telegraph on July 6, 1955, Claire Butler praised "ovens that light up automatically" - an avant-garde invention at a cookery fair she had just visited. She also uncovered: "a pinger which can be removed from the cooker and taken about the house so that wherever you may be, you are reminded that it is time to look in the oven. Another cooker which would be wonderful for those who get into trouble over the right heats. A red light goes on for hot, amber for moderate, blue for very moderate. One oven has a time switch which can also be used to heat a plate warming drawer so that plates and dishes are warmed when the meal is ready to serve."
