The CE2 Oil Kit is an excellent kit, far more superior than the rest. More advanced than its predecessor, the set up is still fairly easy. Pairing with Joye eGo batteries, they will last long giving you endless usage and a higher capacity between charges. The CE2 Oil Kit can hold more than 1.5mL of e-liquid and it helps to produce a lot of vapor. Each package comes with fie 510 ultimate CE2 Clearomizers, two Joye eGo Tank batteries that are lockable, a Joye eGo Rapid USB charger, a mini wall to USB convertor, a 3mL Luer-Lok Syringe, a blunt needle tip and a soft rubber mouthpiece.
