Since this carto is Low Resistance at approximately 1.7ohm per manufacturer, it is recommended for 3.7v devices.
As with all cartomizers do not let it run dry ever.
They will burn, pop and taste disgusting.
Trust me - just don't.
Looow stock on the BLACK
The usual cartomizer DOA warranty applies.
NOTE: please forgive the handwritten "label" on the cartomizers. Normally they are individually labeled but there was technical difficulties with the printer. If anyone knows how to remove a sheet of labels that have jammed a laser printer and are now all wadded up in the runner inside the feed mechanism please let me know. Thank you.
