STAY AWAY!!
Pain in the .... to setup, and even more painful to fill it.
I've got it going in dual coil .7 setup with 28g, but man, filling it was a nightmare. The Chimney covers up 1/2 of the fill hole on the deck, so no room for syringe to get through. Forget about bottle filling, because it just flows back out.
Top fill is almost a MUST for this thing.
Vapes really well, if you can overlook all the building/filling issues.
Lung hitting and massive plumes of vapor with 3mg 100%VG.
I'm waiting to see if the BELL cap makes any difference in the process, or also if I can find a top fill cap. If not.. I'll write off the $20 or so that I've thrown into two of these so far.
Edit: ErlPrinz is WAY easier to setup and can NET the same results.
