I can't seem to make the switch. It's as if I am married to my Pen with the automatic battery. I have tried to use the 510 with manual battery and just can't seem to develop a knack for it. I find it awkward & uncomfortable.
I suppose it's very different if your first e-cig had a manual battery.
How long did it take you to adjust ??
