Great idea, but...

I bought this from STP at least 6 months ago and never used it until this week, when I broke it out to test it in advance of an upcoming trip. Well, even after reading the instructions, following them to a T, and even having a friend try it, I could not get it to work. Even after the prescribed 90 seconds of fast cranking (which is harder than it sounds) the green lights showing the water was purified did not come on. I have returned it to SteriPen.
