Vaped all day on 18mg tobacco from altsmoke in the new lavatube and im impressed. I also bought the 4ml dual coil tube tank and filled it as described on the volcano site and i was extremely disappointed. maybe because its 1.5 ohm and i like 4.5 with this juice. but mostly because a half fill lasted from 9 to 11 which was @ 15 total vapes. is this normal at 3.3 volts? i vaped another 30 or so hits on the cart after the tank was empty and was mildy better. perhaps i didnt "break it in" correctly? after that i popped the 3.3 atty on it and had glorious 4.5 v vapes the rest of the day. by the way,out of the box the battery is still kicking.
