Ok so here's what happened I have the infinity with the 510 connector, I was unscrewing my 510 atomizer which was on there pretty good must have been my Super human strength while i was unscrewing it, I realized that the whole top unscrewd with it I was lucky enough to get the 510 out but now i have the top out with the wires exposed so i gently screwed the top back in, put the batteries back on and press the button **whew still works** yaay! now i just have one problem the top stays loose especially when i switch out atomizers i have tried to tighten it but somehow comes loose again ... any suggestions out there?
