So.. my first e-pipe is the DSE 618. The first time i filled the cartomizer andused it, I noticed spiderwebbing and cracks forming all over the tank. Is there a better tank that can be used with this pipe? I've seen in other forums that the Kanger Protank 2 or3 work well with it. But.. after seeing images of the kanger products, I don't like the mouth piece. Will the pipe stem that comes with the DSE 618 work with those tanks?
