Hi all I just quit a 22 yr smoking habit on Saturday. I did with a standard evod starter set. Although its fine for what it it is I think I am already outgrowing it in terms of battery life and vapour production. I also work on rotation 20 days out 10 days at home, at a mine where it's a hard cold environment with no support except what I bring in to camp. The provari seems to rank high as being indestructible as a battery unit so I am leaning that way, now what carto, clearo, ato,etc is in the same league as far as being bullet proof? I understand that I may need extra parts like multiple evod coils which I am fine with if I know beforehand. I just don't want any surprises when I am away. Any suggestions would be greatly appreciated.
