Good security system so that the child can walk freely but with the security of having it close and child can not cross the street or get lost among the people being with a lot of people especially now that the holidays arrive. Very comfortable for both the adult and the child. It is not entangled because the hooks to the bracelets are articulated and rotating. The child's bracelet is well designed in terms of security because it has double Velcro so that it can not be removed.
