My aspire nautilus does the same thing. I am really going through juice. 30ml in about 6 days. Do you think it is the istick itself? Are you use vaporshark TC coils?
That is what I was thinking was happening last night. I was on my way home from work, my battery was about to die. Before it did, it started just leaking juice. It was dripping down the coils and out the airholes. Even when I plugged it in, it was still just gushing out of the tank. I lost about half a tank that way. Eventually, the battery caught up and it was fine. I was thinking that being low on battery caused it to bleed any time I fired it and that was what was coming through the air holes.the more watts you run it at the faster it'll go through juice.
