Use standard resistance atomizers or cartomizers. You don't need low resistance on the variable voltage mods that are out. However, I've used dual coil cartomizers on mine and it's been fine. As a suggestion, set it at 3.7V and work your way up a little at a time until you "fine tune" your juice to your tastes. Each juice may need to be readjusted but it's worth it to find that perfect vape.
