Review on SABRE PA-USA-02 Personal Alarm with Snap Clip - Ear-piercing 130dB Siren Reaches Up To 1,000 Feet (300M) in All Directions (Approx. 4 City Blocks!) – Enhance Safety with a Patriotic Twist by Chris Benton

The Saber USA Personal Alarm is a great convenience to carry on your keychain. Sometimes I leave the house very early or come home late, so this device is nice to have. It is very comfortable in the palm of your hand. The pin is easy to pull out, but you have to make an effort first. At first I didn't and I had to read the instructions thinking I was doing something wrong. The pin is fully extended and an alarm sounds; put it back and stop. Although the alarm clock is not very loud. Loud enough to draw attention when in a densely populated area. But if you're outside and people are inside, they might not hear you. We didn't hear anything in testing, but it's better than nothing and you never know who might hear it. Patriotic design is cool too. People will ask you what it is. It snaps easily into place and has a built-in rechargeable battery so you can start using it as soon as you receive it. By the way, the battery is 12V. Decent buy, just don't expect a megaphone.
