Replacement dual coil heads for the Innokin iClear 16 and iClear 30 Dual Coil Clearomizers
This often comes down to personal choice, rather than being forced too because of a sudden failure.
When e-Liquid is vapourized, what isn't vapourized is left behind, and that is left behind on the coil, also on and within the wick.
This will at some point start interfering with the quality, volume and overall taste of the vapour produced.
So based on that, treat yourself to a fresh head when the vapour and flavour production fall to unsatisfactory levels and or with each flavour change in ideal circumstances.
You might be suprised at just how much they can change with use.
NB: The iClear base, body and tip are not included.
