I just bought a blucig starter kit, just to check it out and see if I liked it. (I appreciate recommendations on other ecigs, but not in this thread) Here's my issue; Following the directions given to me both on the website and in the materials, I tried charging the pack using the USB and the wall charger. The light on the pack DOES come on...but only every few seconds. It's like a slow flash. Does that mean it's charging? Charged? Busted?
