Great idea, but.....

Why wouldnt they just have a power on/off button? I keep wrapping and unwrapping the device as instructed, but it still wont turn on in my phone. It worked really well on Day 1, but on day 2, Im thinking of returning it. Im saddened, because I personally think it could potentially be a lifesaver.
