I can imagine permanent damage even if it is removed fast. Plastic hooks that go into the skin. Tell me that you would actually be able to get fast help with that kind of pain. It's a great idea, but sounds costly if you're the person that would wear it. I mean it's meant for party people or people that travel a lot. People that are at higher risk for rape. So one a day can get expensive. Just like that Star Bucks once a day...
