I used this on an overseas trip. My children are 9 and 7 years old, and I attached it because I was worried about them getting lost abroad. My older child is already big and initially didn't want to wear it, but I told them that if they got lost, we might never see each other again, and they agreed to wear it. We call it "handcuffs" at home and put it on them while saying, "I'm going to arrest you!" It was only used for 3 days during the trip. If you can't imagine your child running out and getting into an accident, this is for you. Sold as a set only. The orange is not included.
