Designed with ease of use and maximum flavor in mind, the new iSub Apex Tank from Innokin represents the latest in mod tank technology. Solid spin top-fill capability and a no spill coil swap system makes refilling and replacing coils incredibly effortless. Additionally, the advanced new Prism Flavor+ convection system boosts e-juice flavors to their max, delivering an unprecedented burst of taste with each vape.
Note: The iSub Apex is backwards compatible with all Innokin iSub coil heads.
The best of the best will recommend it to all my friends just the price is a little high
Best tanks ever. Can't break them. Easy to fill. Only worthwhile tank out there.
