This easy to use automatic timer for electrical appliances is a simply way to gain safety and peace of mind in your home. There's a choice of times ranging from half an hour to eight hours. If, for example, you are going out all day but want the oven to be hot when you return home, you can select the eight hour setting so it comes on just in time. If, alternatively, you are ironing in a hurry and think you might forget to turn it off, you can set the timer for an automatic turn off after say, half an hour. For added security you can use the timers to set lamps to come on in the living room in the evening so it looks as though someone's home. A useful gadget with a variety of functions.
