I've been vaping for about 6 months now, using an eGo (and clones from GP, their eCo). I mix my own DIY e-juices, and also use some bought juices. I've tried atty with cartridges, drip atty, and cartos. I'm finding that no matter which hardware I use, I can't get a consistency of flavor from the same e-juice mixture over the course of even one day. I have tried many different hardware cleaning regimens, and different brands of attys and cartos, but nothing works to make e-juice taste the same, when using exactly the same batt/atty or carto/e-juice bottle combination. The taste just changes on me, even when using the same 30 ml bottle of juice mix. Is it me, am I doing something wrong, or is that just "the nature of the beast"?
