I had just bought a carton the day before I picked up a swisher sweet ecig, 3 days later after dealing with 3 hour battery life issue, I broke down and picked up an Atmos v2 Thermo (didn't know its primary use at the time) lucky it is a liquid tank atty. Now I'm waiting for my Zmax v2 and ALL the hardware. Mind you, this journey started 8 days ago. Plan on giving the atty to my wife so she can quit smoking too, just gotta wait for her juices to get here.
