Give yourself security, even on the go with the Streetwise Panic Alarm keychain. The item features a fast and simple "squeeze and scare" operation that allows you to quickly activate the alarm at the same time you clutch and squeeze the device. When the alarm is no longer needed, simply turn it off by pressing the gray center button on the top. When the device is not sending off an ear piercing alarm, you can press the center button for an ultra-bright LED for nighttime safety. You can attach your alarm to your keys or even clip it to your clothes with its metal clip on the back, keeping it always within reach. Item includes (3) three LR44 button cell batteries.
