  2. Swann - ActiveResponse Personal Safety Alarm Keychain with 110dB Emergency Siren - Black - Front_Zoom
    Top comment

    "Very Useful Product But Not Very Alarming...Not sure how effective this will be. The most useful part of this is that you can set up emergency contacts and this is where this device will shine if people know you have this and hopefully they will pay attention to this. ...Sending the text to your five contacts is avail without subscribing to the Swann plan. This alarm would be useful to most people and is very clever. You can attach it to your kids backpack, or give one to your loved one during runs or walks. "
