This does work - I carry 2 with me, haven't smoked a full pack of cigs in over a month and I was a pack a day smoker for about 20 years
I use an EGO T 650 or 1100 (bought an extra bigger battery) with a Tank for my main and a Halo G6 as my back up for running around public places, bars / clubs / dinners etc. Both have great throat hit and huge amounts of vapor that satisfy me. Smoking analog cigs is in the past and I feel 500% better just after a month!
Both starter kits above... $65 or lower - Google it if you want to try
