When you receive the Firebox you get an atty with it but this didn't seem to hit my
vaping sweet spot.
I've tried a eBarron spiral and a Killer 705 in this
mod and they both fit.
The Spiral just fits inside the bowl and connects to the 510 connection without any issue but the fit is tight which makes airflow rather tight. However the Spiral is a larger atty and therefore gives you longer vape time between sqonks.
The Killer fits and works perfectly as a bottom feeder. The airflow is good and the sqonking concept also works correctly. However due to the design of the Killer (having a wide section in the middle which houses the ceramic/coil) it does mean the cone supplied to prevent leakage from over-sqonking does not fit. I would recommend getting a Diver if you want to make use of the cone.
In my opinion I think the Spiral looks better on the Firebox but that is my humble opinion. I'll keep road testing these two atties for a few weeks and report my findings if anything crops up!
