The KizON wearable also features a ‘One Step Direct Call’ button, which lets parents contact their children easily. If the kid fails to answer a call from any pre-set phone numbers within 10 seconds, KizON will automatically connect the call so the parent can listen through the built-in microphone. Kids can also dial a pre-configured phone number in case they need to speak to an adult.
Good idea, but the device is too big. I don't think it will fit on my kids' arms. I don't think I can convince them to wear this either.
