Let's start with what this product isn't. It's not a hard candy in the shape of a battery. It's not a battery-powered defibrillator, capable of saving your life. No, it's something much more important: the Dynafit Batter Life Saver will save the life of the battery in your Instagram device! Use this Social Media Life Saver to keep your phone warm and photo-ready, because if you didn't get the shot, did it even happen? As a bonus, you might extend the life of your navigation device which, in theory, could save your actual, real, in-person, physical life.
