I was never a heavy smoker but I'm glad I made the switch to vaping. My ego-c and mini vivi nova tank are working out perfectly, and I'm already thinking about upgrading to a vv! I'm eyeing slb's ego-v v2 for now. I don't think the problem is going to be me running out of juice; it's going to be me wanting to spend my money on upgrades all the time haha.
