This is some legit cool stuff. Carrying a cable like this is much easier and you never invite much attention in a hurry. It's also a nice way to flex around your friends when you take off your bracelet and tell them it's a charger.
A cable that is wearable isn't going to be one of those that break easily. Even without the wearable aspect it's still a lot better than a normal cable. The price is ultra cheap at $6 for earliest buyers!
