Welcome and glad you joined.I've noticed that with the new istick 200w (i run it really low, using a .3 atomizer non modded, 3 samsung 25r batteries) crackles and pops to the point that it is slightly painful. I've had different vapes over the past two years but I don't "mod" and am not extremely knowedgable about all this stuff.
Not all my mods do this. Maybe my coil is old? Or getting oil? There's enough juice and everything too.
