Background: We have in the bedroom closet with sensor-controlled interior lighting (door is opened, the light comes on). Because the cabinet doors are glazed, "think" the sensors in bright sunlight, that the door is. Result: the day is on the closet light.
The timer is easy (using the instructions) to use, I have to change batteries (integrated battery for power outages) and turns silently. And at this price.
I have no more demands on a timer.
