L: Kanger EVOD tank w/650mAh battery; R: Kanger Pro Tank II w/900mAh battery.
Having leakage, battery issues (stripped threads, won't charge, etc.), I slipped into buying some cigarettes the last few weeks to get my blood nicotine at maintenance levels. Trying to get back on the wagon. Still need another battery or two, I think (the two above are the only two reliable ones I have), and I still have to figure out all the tricks of the Pro Tank (Pyrex™btw, and heavy duty), but Ivy's an expert with those, now.
