Is there ANY sort of tank or clearomizer out there that doesn't require some god awful amount of tinkering besides cartomizers. I got a box of phoenix 1.5 ml. First one tasted perfect until a refil, now all three that I've used taste like crap and still taste like that after clean and dry burn. I really just want something with no filler that I don't have to mess with every 4 minutes so it tastes good.
