The Vandy Vape Berserker MTL Starter Kit is a discreet vape pen system, featuring a 3.5mL max fill capacity, integrated rechargeable battery, and five adjustable bottom airflows utilizing a dedicated Berserker MTL Coil System. The Berserker MTL Starter Kit comes with an optional bubble glass that nearly doubles the standard capacity to 3.5mL, thanks to the convex curves of the bubble glass. The BSKR Berserker MTL is powered by an integrated 1100mAh rechargeable battery, allowing the user to have a long lasting vape experience. In addition, the LED battery indicator lights that surround the intuitive firing button will change colors to give hint to the mode or status of the battery, while giving dependable feedback to the user. Furthermore, the Vandy Vape Berserker MTL Kit has a plethora of air flow controls that can be adjusted by increments of 0.2 millimeter dependent on the strength of nicotine salt within. The Berserker MTL Kit can be refilled by unscrewing the top cap and removing it to fill from above. The included Berserker MTL SubTank is constructed to use a wide range of eLiquids and Nic Salts, including a pair of 1.5ohm Berserker MTL Coil and 1.8ohm Berserker MTL Coil working in synergy with the airflow for desired vape experience.
