We brought one for our DS(3) who has a tendency to dart around people and run off given the slightest provocation. Unfortunately, he wouldn't wear it
so he was buckled in his stroller most of the time. I did consider putting the tether on my husband, though..he also has a tendency to disappear (although he doesn't dart around people like my son does)...so I would definitely say get one for your children and one for your run-away spouse
