I bought 5 of these to turn on all my Christmas lights hoping to 'set and forget' them with the twilight and X hour features. They seemed to work for the first few days, but I didn't pay much attention to the shutdown time. Now, a week later, however, the shutdown feature works very inconsistently, with each unit shutting down at a different time. I wired them all up and taped them to different mounts so it would be very difficult to remove and return them but I don't see an alternative as they don't work as advertised.
