Wotcha one and Wotcha all....<deep breath> I'm currently using a Britvapes v6 and Argento, a couple of ego passthrough batteries, my own 4.2v AAA mod, mostly through vivi nova or using up my old supply of boge lr's. I started toying with vaping about 18 months ago and finally took the plunge and stopped the fags about 4 months ago and I've started mixing my own flavours recently with varying degrees of success. And I am VERY interested in hearing from anyone who has tried one of those 8400mAh jobbies, amongst other things.
