So I bought a pass thru a few weeks ago... anyway, it has been collecting dust since it will not work with any of my cartos. It worked well with a few older reg cartos... well they are all dead and unavailable for purchase. All I had from V4L were the gold soft caps and it just doesn't work with those. Anyway, out of desperation to use it I (please don't thrash me!) ordered some Mega Cartomizers from another vendor. Guess what? They don't work either. How can it work with the old ones and not the new ones? I really don't want to ask for a replacement as I have already had to ship back 3 batteries in the last 6 weeks and they are going to start seeing my emails and think "Oh no, her again!". Anyway, I even tried messing with that little screw thing on the bottom in case it wasn't making contact. Having seen people advise against it I was hesitant to fiddle too much but figured it was worth a shot. Before, I email them is there something I am missing here?
