This product cannot be exchanged, otherwise I would click on the return of the goods and not write a review. I use a timer in my greenhouse to keep the lighting optimal for short days and long nights. This timer turns on in the middle of the night, then turns off when it should turn on, then turns off at noon, then turns on again when it should turn off. To me or anyone trying to use this timer fictionally, this timer is garbage. However, if you don't want it to work properly, this timer does just that.
