This is why I have made my decision to buy the Provari. Anymore, I research almost everything I buy, sometimes obsessively. I have been using a Ego tmod for six months now, it was my first pv, and it took me a month of research to decide what to buy. It is failing me now and needs replaced. So I'm back to research, at first I wanted a Vamo, then the anyvape cvi, the the evic. But I have seen too many reports of failures with all of these. So aim am buying the Provari for its durability, warranty, customer service, performance, and good ole Made In The USA.
Now I just need the money. Lol
