In urgent or dangerous situations, people tend to lose calmness and control on their bodies.
The Alarm Ring is able to send out an emergency message at top speed with a very simple action. Even though you’re controlled or threatened by somebody, you can send your distress message by double clicking the button on the ring, which is a small movement that won’t be noticed by the criminal. This distress message will notify the police that you are in danger. After that, the police can locate you and come to save you.
