2) What kind of electronic cigarette are you currently using and do you switch back and forth between other models/setups?
I still have my original 650 mah batteries (2) that I've been using for almost a year and one half, I use these along with 4 other ego types, mostly for travel. I also use in between these, my vv lava tube and a few other vv mods with 3.5 ml tanks for the mods and 2.0 ml ones for the egos and I have about 12 of these tanks and many batteries and chargers and a lot of juice and much storage!
