i have settled down these days to a couple batteries, itaste vv/vw 3.0 and ego mini. A couple tanks, Pro tank and a couple evods and that is it. I use the mini at the ballpark and places you dont want to be seen. I use the Itaste and Protank everywhere else. I bought some extra coils a few months back. 3 bottles of cinnamon juse and i have not bought anything for a long time. I will buy some juice, but that is about it. I just decided i wanted it simple. if i use same juice and battery i dont have to change it out very often. Simple is cheap, and that is good.
