In the words of Cervantes, "To be prepared is half the victory." Go out and live your life without worry, but be prepared for disruptions that may come your way with this personal alarm. Press the front button and this small box with a BIG voice emits a 130dB alarm letting anyone in the vicinity know you need help—and hopefully scares off any would-be attackers. A small button on the back deactivates the alarm, so if anyone wrangles this device away from you they will instinctually deploy the large front button to turn off all the noise, but to no avail. This self-defense tool also has a keychain attachment and an integrated whistle, in case you need some more low-key assistance. The spray reaches up to ten feet.
