So... I got a smok Vivi tank to play around with and figure out this coil/wick rebuilding thing while I wait for my better rebuildables from fasttech... I Just wrapped my first coil and put it on my SVD (with 18650 Efest) and check the ohms and it says .9.... So is that safe to vape? Or should I be aiming for a readout of like... 1.8-2.5 like replacement heads that you'd buy?
