This juice is like the first cigarette from a fresh pack of Marlboro Lights in every puff! I started with the 6 mg and found myself still wanting cigarettes now & then, so i bought the 12 mg this time- that was kind of strong so I mixed the two and Perfection happened! I change my cartridge after every third refill for the best flavor. Thank You Black Note!
