How do I refill devices and cartridges?
They all have different options, but the latest method is even cheaper, allowing you to buy little squirt bottles of nicotine juice, and then saturating your own cartridge.
I haven’t tried that yet, but intend to soon. For now, I just buy the refill cartridges from the device vendor, which pop right into the end of the electric smoking device.
That’s easy and fast, allowing you to change to a new cartridge in about 10 seconds.
