I don't even remember what I was reading when I first heard about e-cigs, but I remember exactly what went through my mind.
First I thought "Do
what? That won't work!"
Then I thought "Hmmm--I gotta try one of those things!"

(I love gadgets.)
All the talk about atomizers and batteries and juice--may as well have been in Hungarian--so I chose a 2-piece model which shall not be named here. I really just wanted to see if the thing even put out vapor. I had no intentions of using it on a regular basis, or even after the cartridges ran out. I just wanted to play with it.
When my new toy arrived, it took about an hour after the initial charging to realize these things had *promise.* The flavor of those first cartomizers was somewhere between air and an old breath mint you find in a drawer, and I wasn't very good at exhaling vapor, but I was getting sufficient nicotine to keep me from smoking analogs alongside the e-cig.
I knew I wasn't doing something right when I found videos of people demonstrating them. I was also able to figure out that all the atomizer talk wasn't something I needed an engineering degree too use, so I ordered a 401 kit. And an 801, too...
Then I found this site and was able to ask questions. My main question was "How come these videos show massive plumes of vapor, and all I can get is a piddling little cloud?"
That was the first I heard of the learning curve, and thanks to the helpful folks on here I was able to correct my errors.
If I had just been turned loose with the things with no one to help, I would have kept them as a conversation piece, but not used them regularly at all.
As it turned out, though, after the first week of being told what I was doing wrong I preferred vaping to smoking, and within two weeks I wasn't smoking cigarettes, I was vaping exclusively.
I don't remember how many people I have given this site to, and vendors that I can personally vouch for. I do know some of them have actually started vaping and passed their new knowledge onto others, though, even when they did not necessarily keep it up.
The people that I *know* gave it up were those who gave themselves weird deadlines--like "When I get it, I am never going to smoke again" and then two weeks later would say "Now I am going to stop vaping, too!" And within two days were crying that they were back on analogs. (Why they went back to cigarettes instead of back to vaping, I do *not* understand.)
But this site is wonderfully helpful. And so are videos that
demonstrate how to use them. (Videos that just show people vaping and issuing forth massive vapor clouds have amusement value, but are of no real help.) Spikey had videos on here when I first came on, and she showed how to clean them and everything--her videos were a great help! We need more like that.
I think a lot of people give up out of frustration that is totally unnecessary.
(Just for full disclosure: A while back I started smoking one cigarette per week, just because I was turning into a big horse's rear end when I smelled smoke. I never said anything to anyone, but I thought a lot. So I *try* to smoke 1 cigarette a week. Most weeks I don't smoke one, though.)
