My blu electronic cigarettes are not working properly. I bought a pack and plugged it into the usb of my computer and into my iphone wall charger and at some point the pack stopped charging the cigarettes and just stopped charging and ighting up all together. So i bought another pack and and one of the batteries (long cigarette part) also seems to not charge, when i plug it into the pack, the red light on the pack blinks a little bit and then stops. Also the batteries from my first pack do the same thing in my new pack-charger. Only one (out of now 4) of my cigarettes actually charges and works. The pack is a blu starter pack, it has one column and 5 slots. I have been endlessly searching for answers on the internet but its so frustrating that I can't find an answer not even on the blu website. If this continues I'm going to buy a high quality vaporizer. This all happened within one week.
