What I would like is not something that allows me to track my kids 24/7. But I would like a device my kids could have, when they are lost, or an emergency, or they need me to locate them, they can press it and it will then share their location for the duration of that event. Pretty much just an SoS device. Addition: Even outside of just the kids. When my wife works a late shift at the hospital, she would like a device like this for the walk in darkness out to her car in the parking lot. Or similar situation where she had to do an emergency road trip to handle an emergency with her dad and would like to have a device that can alert me and temporarily give location if she needs top stop and get gas at 2 in the morning.
