invisawear Smart Personal Safety Necklace

Here is a necklace that you can wear anywhere to get help when in trouble. The invisawear Smart Personal Safety Necklace sends a text with your GPS location to five people that you know with the double press on the back of its charm. It uses the same emergency response tech as ADT. It uses Bluetooth and works with your phone to let you choose who you would like to notify.

The battery lasts up to a year and could be longer depending on use. More information is available here.
