The timer is very well made and work with us to control the espresso machine that needs to be turned on in the morning half an hour before operating. This works every day without any problems. If you want to take the device outside the switching times in operation there at the top left wheel with "0" and "1" function. So you can cut short the set switching time and make the device individually in operation. Then again provide the setting wheel to "0" and the timer jumps at the programmed times again. Simple and practical!
