Let me elaborate I have found my favourite liquids I have found my favourite pv ( my provari ) but I'm still looking for the way to bring them two together to make my vaping experience perfect I've mostly been using my vivi nova for out and about and my cobra for at home but they both have there flaws I really like tanks but found it reduces my battery life to practically nothing what's everyone else stuck on the end of there devices and wha are the ups and downs of it ?
