Personal Alarm, JDDZ 140db Safe Siren Song
Personal Safety Alarm 2 Pack , JDDZ 140 db Safe Siren Song Emergency Self Defense Protection Device Anti-Rape / Anti-Theft Security With Mini LED Flashlight for Women, Kids and Elderly etc. However, from the Siren Song alarm reviews online, a lot of users complain about it not having instructions in the pack. You just pull out the chain to set the alarm off and then put it back in to turn it off. Louder than a whistle and small enough to carry it with you all the time.
