It can be a pain to get the wick right but once you do it shouldnt leak...its 3 rebuildable decks now (not that im toutching the triple coil.
i had 1 build that lost al its liquid in a night, and an accident opening the top in pocket that spilled all liquid
for the rest it has been rock solid
i absolutely love the tank.
Still fiddeling to get a good dual coil build, but the tripple coil heads are perfect for me (loads of juice dont use it if you don't mix your own ;p )
