Great device as long as it works! I did it for the automatic shutdown of my coffee filter holder in use. Unfortunately, it is with me like some other buyers also: The timer is only 8 months now use defective. Sometimes he works as normal, but every few times it connects through no electricity and it's always a surprise when you turn if it works or not. Therefore, I will return the timer and hope that Amazon is accommodating in the settlement of claims. I will keep you informed of developments to date.
