Stylish, and functional, the K2 has many of the features that you’d find on an expensive sub-Ohm tank. The K2 is fitted with a luxurious, stainless steel drip-tip. The drip-tip is a replaceable ‘510’ type, so it’s easy to swap for a custom alternative. Airflow is pre-set for relaxed, mouth-to-lung vape – a lot like a filtered cigarette. This is a ‘bottom-fill’ glassomizer. After unscrewing the bottom section, you simply drip your e juice down the inside of the Pyrex glass. That Pyrex glass is an important feature! As well as being tough and heatproof, it also resists acidic e juice flavours like spice and citrus fruits.
