Man, I've tried everything I know to stop this from happening and it still does it - not all the time but a lot of the time. I do not overfill - just to under the silicon cap, I don't overtip (just to get the wicks wet again) but ... bloody hell ... I love these things except for that one problem. Anyone else have this issue? I suspect not many as I don't see that bantered around much. The juice HAS to be coming down from the metal tube to leak through the battery end, right? Geez ... I'm extra careful to NOT over tip! Thought maybe it was when I was refilling them and getting juice down the tube but it can happen at any time. Any other tips/suggestions as to what I might be doing wrong? I know it's 'user error' ...
