The beauty of buying empty cartridges for your Electronic Cigarette, means you have an empty ready to fill cartridge for any flavour or strength of Genesis E-liquid you wish to vape(smoke).
Re-Fill the cartridges time after time, changing every 10-15 top ups, this is really down to the individual but we feel it to be a good recommendation as the lint gets tired and clogged if over used. Potentially an over used cartridge could damage the atomizing unit of your Electronic Cigarette.
The MINI2 Electronic Cigarette Re-Fillable cartridges can be used with Genesis MINI2 model.
