14 days and no analogs. Easier than I expected, but I have like 8 ego-style batteries (650 to 1100mAh) , a lavatube, a provari knock-off, 6 or 7 tanks, 20 or so 510 atty's, and about 50 "clearomizers" (8 or 9 with different juices). It's an initial investment but it's all been kinda "free".......with a little help from my friends.
