We've sold over 500,000 alarms in the last decade, and this may be the best design yet.  Not only does it have a bright red LED  locator emergency signaling flash light (that literally takes up the whole back panel of the unit) but the alarm has a new design tab-pull style that solves problems most other cheaper alarms have.  You can't lose the pin as it never is disconnected from the alarm.  

This alarm has a tab-pin activation.  Pin pulls part way out, eliminates accidental activation and potential loss of the pin.

Personal alarms are legal to carry in all 50 states (even on airplanes!) and are a very safe and effective method of self defense. They require no training or skill to operate, and can be used by anyone regardless of age or physical ability. Police Officers, Campus Safety and Security Consultants recommend the use of personal safety alarms.

This is the white version.  Also available in black(sold separately, model KG-DS12B)
