Personal Safety Kits has a very popular personal alarm unit that not only let's others know that you are in danger, but it also can detect movement and guards your stuff!
The Mini Personal Travel Alarm with Motion Detector, has a 100dB personal alarm that notifies others when you are in a dangerous situation and need self defense. Plus, it includes a motion detector to let you know if someone is touching or getting into your stuff!
This unit is perfect for personal protection, because you can pull the top pin up and it will let others know that you are being attacked or have some kind of emergency! Besides having the main functions like the 100dB personal alarm, it also has a motion detector that can sense movement 10 feet away! Placing the Mini Personal Travel Alarm with Motion Detector next to anything valuable that you have, will protect it from being tampered with! If someone gets within 10 feet from your stuff, it will sound off the 100dB unit. This in turn will let you know that someone is tampering or stealing your laptop, purse, opening a chest drawer, or whatever you placed the unit next to! So... It offers self defense and protects your items!
