I’m 53 years old and started smoking when I was 18, 1-2pack a day Marlboro smoker,tried everything to quit, tried Juul 1year ago and have not even craved a cigarette!! No problems with leaking or no battery-device issues at all! I’ve read comments about leafing and not enough vapor, I think the pod leaking bitches are anal retentive! And for people moaning about not enough vapor, it’s not designed for that, if that’s what you want go get a big chunky mod box contraption! I think Juul is a great company it sure as hell helped me guit smoking! AND IT IS CHEAPER than smoking!
