Recently I purchased a herakles sub ohm tank and absolutely love it except for one thing. I have to hold the fire button down for a while before the coils get hot enough to actually produce vapor. Is this normal? I'm using the stock .6 coil. My atlantis gets hot enough right away I use a .5 on that...my device is a simple dual 18650 parallel mech box mod
