This wreath on Wayfair's site says it runs on a timer. it arrived today with no other paper work but sales' slip.....it is full and looks pretty realistic...lightning button turns it on but if you lean it against anything, it goes right off....so if you hang it on your door, as most people do, make sure the battery compartment is not leaning on the door, but tuck inside with light button free of anything pushing up against it....it is pretty when lit.....now if we can only get the directions how to set the timer, we can give it a better rating...unless it was a return, why would it not come with directions?
