Meet the Guardian Angel Jewelry: a smart wearable that helps you get out of uncomfortable and dangerous situations. You can wear this like a bracelet or pendant. It works with its companion app to help you make a fake call to get out of an uncomfortable situation. It all happens with the push of a button. In more serious situations, the wearer can send a SOS message to a contact with her GPS location.
The Guardian Angel kit includes a pendant in Sterling Silver, and a 27 inch Sterling Silver chain. You can also get a silver bracelet and leather cord, but those are optional. This wearable item sets you back $120 + s/h.
