Strong performances without damaging batteries...As using clearomizer coils with resistance values that are too low (less than 1.0) tends to damage the devices if sub-ohm compatible batteries are not used with, JUSTFOG®USA has found a way to offer performance with a resistance value of just 1.6ohm that can be used in normal batteries as well.
