Hi, I am on a very tight budget first off. Ok my very first setup I went to a local shop and they sold me a ego-c twist with and ce4 well let just say i went back to the 808's. I went back to the local shop and they said maybe get a different tank like this pro tank mini we have here for only $21.99. I said well why didn't u tell me that when i was here the first time. Well i didn't get it at the shop but i found in on ebay for $12.49. Well what a differnce. My question is what for be a better battery for the protank mini than the ego-c twist and remember i am on a budget and I do like the VV option because some of my juice vapes better at different volts....Thanks
