The whole mod/kit? If you're buying one make sure it's the V2 as they originals had dodgy paint.
like @JohnNada said bud make sure you get the V2 version i sold mine on, anyway which vendor you going with ? ive found ecigone very decent & if you get any probs the owner Ellie really does go above & beyond.
I don't or should i say can't use Ecigone so i never even look at their stuff now, I think i saw their ad and it was £14 more than i can get it for, i think they are getting a bit expensive compared to others i use. That's just my opinion though.
thats fair enough mate either way you are going enjoy it
