The 0.25ohm and 0.5ohm replacement heads use stainless steel wire, whilst the 0.8ohm coils use kanthal wire. Vapers that want ample plumage will go for the 0.25ohm coils. The 0.5ohm coils offer a balanced vape. Lastly, the 0.8ohm coils offer the best flavour and longest life of the three.
PLEASE NOTE: These coils are designed to fit The Uwell Crown 2 Tank and Crown 2 Mini only.
