Technology is an amazing thing. With it, we'll never need to worry about a repeat of the Great LOLcat Shortage of '94, and we'll always know exactly when our bestie's baby spits up all over daddy.

Advancements in technology have also enabled us to develop things that are actually useful.

Introducing the Guardian Angel, a pretty sterling silver pendant that can also be worn as a bracelet... and could someday prevent you from being raped.

The device, in conjunction with the Guardian Angel iPhone app, can be used to trigger a fake phone call that will provide a diffusing distraction in an uncomfortable situation. It can also send an SOS message to a designated number of your choice -- your best friend, your mom, whoever you trust most in the world -- with a link to your GPS location, to get help on its way. It even has several interchangeable chains and bands to suit your personal style.

At a $120, the pendant is a bit spendy, but that's a small price to pay for a little piece of mind.

Currently, the Guardian Angel app is only available on the Apple App Store, but here's hoping it'll be available for Android and Windows soon.
