Child safety alarm that protects with a 100dB volume. Used a few times. I checked the operation when listing it, and it's a great deal. I think it's good for children's commutes to school, and for adults to keep by their bedside in preparation for burglaries, robberies, etc. To avoid trouble, please refrain from purchasing if you are overly sensitive, seek perfect condition items, or tend to make claims or request returns over minor issues. #SafetyAlarm #BurglaryPrevention #RobberyPrevention
