I did only have a couple of vapes using it though. And it actually seemed to stop working when I was rebuilding the 0.3 ohm coil, sometimes the rba would fire but sometimes it wouldn't and I'd have to adjust the bits and pieces of the coil for it to fire, then I put in my 0.5 ohm coil and it was a no go.
A couple of vapes is all it take to expand the coil.
Hmm, even the 0.5 isn't working now, but it works in other mods...
So, the tank works on other mods, but not on the Subox, and the ohms read fine on the Subox...
Is that the present issue?
Have you tries other tanks on the Subox? Sounds like the tank is ok, now lets see if the Subox is the issue. This is where a multimeter would get you the answer right now. Do you have access to one?
