There are a lot of people in this forum that keep repeating that DC cartos work great on ego batteries. They do work, but they do not work to their full potential and I think they cause a lot of people to judge the entire concept of vaping with a carto/tank based on that less than optimal experience. I think Smoktech would have been better advised to market their tanks with the resurrectors because their new customers trying the tank/carto concept for the first time are nearly all are low voltage vapers.
I actually like the dual coils especially with certain flavors, but only at a minimum of 4.5 V for a 1.5 ohm, but 2.0 SC boges and 1.5/1.7 SC smoktechs are still better on a 3.7v device than a DC on any setup.
