Explain the difference between the cartridges!
Q. What's the difference between the cartridges?
Smoker's HALO Standard refills: These last for 200 puffs. They have a steel casing, replacing the plastic casing of the NJOY, which prevents the overheating and breakages experienced by other model.
Smoker's HALO High Capacity Refills (best value): These super long-lasting refills last for 400 puffs - twice as long as regular cartomisers. These do not yet come in zero nicotine strength.
