Light is beautiful but you get what you pay for. Plastic screws are provided to adjust the length of the lights. One didn’t want to go more than half way through the hole so we ended up having to rig it with a rubber band, tying it on the inside so the rope wouldn't slip through. Maybe we just got a dud screw because I don’t see that anyone else has had that problem. I guess I hoped the self adjusting lights would have been more durable and not have to worry about them falling through in the middle of the night.
