I have to comment on this topic.
I've had the Silo Tank since Sept or October and It hasn't missed a beat, it was so good I bought another.
Both work perfectly with the Nautilus BVC coils.
None of the crackling and spitting I get with the Atlantis.
A tank of juice will last all day, with the Hana Mod V3 set at 15watts produces a lot of vapour, not quite as much as the Atlantis, but almost.
The only flaw I've had is after a while, the base becomes hard to remove to refill, and occasionally needs pliers to make the first turn.
The Nautilus BVC coils last around 2 weeks.
The Silo works well on the istick and Hana V3.
I have the Atlantis, Lemo, and the Kanger sub ohm, all fine clearo's, only the Lemo is satisfying as my Silo Tanks.
The Silo produces vapour similar to what it feels like smoking a cigarette, I recommend it to those still trying to quit tobacco.
