I bought the timer socket for an electric blanket. The easy to use, even in the dark, the unit is thoroughly recommended. It does what it should. The settings are probably some limited, but that's what makes it so easy. How else at night without the lights turn on, sometimes just turn on the electric blanket for one hour? This is simply by pressing the only button (of course, I must here press the button three times; 15, 30, 60 minutes). For me, therefore, a perfect score.
