We interviewed lots of people, and found out that many of them grab hold of their keys when feeling unsafe. We understood that the feeling of confidence and emancipation that comes from being prepared is an important factor in avoiding unwanted interest. Having the Hit Personal Alarm and key holder near at hand helps you being prepared and gives you that feeling of confidence. The Hit has a built in alarm that activates with pushing a button. If you pull the thread the key attaches to the Hit and you will have an alarm and defense in one!
