*  This high-tech security alarm transforms an ordinary doorknob
     into a highly sensitive burglar alarm.
 *  In order to gain easy access to your home burglars will first try
     your doors to see if they are unlocked.
 *  If a burglar touches your outside doorknob this device will instantly
     emit a loud alarm to scare him away and alert you to the attempted
     entry.
 *  Unlike other alarms, the burglar will be stopped before he enters
     your home.
 *  Even if he is wearing gloves, the alarm will sound as soon as the
     outside doorknob is touched.
 *  No installation required: simply hang on the inside doorknob of
     any wooden door.
 *  Please note that this alarm will only work on wooden doors.
 *  Requires one 9 volt battery (not included)
 *  Alarm on/off switch
 *  LED power indicator
 *  20cm string
