I'd tried the NJoy last year, but it gave me no joy.
In an effort to save some dough, and after seeing a very quickly increasing number of people vaping on the street here, I picked up an eGo Twist and some 24mg juice. After 28 years, overnight I immediately became a non-smoker.
After a week, my disposable tanks crapped out, so I moved to a Kanger Mini Pro II. The problem was that at first I couldn't figure the thing out (yes, I now know it's quite simple), but had to smoke an analog. I could barely get halfway through the thing, it was SOOO heavy and harsh and rather brutish in comparison. I figured out the tank issue, and since then, not a single analog. What's more significant is that it'll be too soon if I never smoke another analog ever again. And this after a pack a day for 28 years. This is a miracle. I'd always stayed in pretty good physical shape, but now it's all even better - no cough, clear lungs, etc.. And no smell, and even with the up-front hardware costs, still saving significant cash.
This is like going from coal to natural gas overnight. I have stayed with the 24mg mix, because it is a pleasant little jolt, or even better, a pleasant big jolt with an adult beverage or three.
An issue, and a fun one at that, was how to pair the juice with red wine. The mint was fine during the day, but with red wine, and most food for that matter, not so much. I now have a lightly sweetened tobacco flavor that goes wonderfully with the vino, and tastes very lightly of maple syrup.
I'm also not into the huge plumes of vape (just the nicotine please), but this is all also so much more pleasant than analogs on many levels.
I'd also the thought of a possible pairing chart with different cocktails, i.e. find some savory herbal juices that would go with infused simple syrup gin cocktails, for example. It seems that this could be fertile ground for the hardcore beer geeks (no shortage of those around here); pair the brew with the juice.
