The Juul is great when it works! Sometimes the whole pack of cartridges are “syrupy” and unsmokable . Sometimes the chargers work and sometimes they don’t. Sometimes the Juul charges and sometimes it don’t. It’s just not reliable. If you’re a diehard cigarette smoker trying to switch to the juul I suggest you buy five juuls and five separate packages of cartridges so you can to get your nicotine fix.
