There's nothing wrong with starting with the cig-a-likes. Hell, I used 2 brands of them before I've now moved up to eGos..and later I'll move into the APV's.
I started with the Blu near the time they had only been around a few months. Was new tech and the batteries were horribly short, some carts didn't work etc etc. Blu is still problematic. That being said though, I did find that I had dropped off analogs completely for a period of about a month or so (pack + a day smoker here) and was fully onto the Blu, till it crapped out on me and I went back to analogs.
Then I was seeing the cost of cigs going up (again) and thinking about my money and health along with other changes in my life, and remembered that I did stop smoking entirely for a short bit there with the Blu. So I started looking around. Checked out companies like White Cloud, Halo, Revolver, etc. I decided the Halo G6 looked pretty good and decided to give it a whirl. Starter kit was $55 and came with 2 (200 mAh or 280mAh) batteries, case, 5 pack of cartos etc etc. It's an 808 threaded cig-a-like offered in a variety of colors and options. So far, for me, it's been performing pretty damn well. The batteries have lasted longer than I was expecting, vapor was very good, and the flavors are all pretty tasty to me. I'm keeping it as a backup, or maybe passing it on to a co-worker to try or use it to start my old man on vaping perhaps.
A lot of folks on here start with the cigalike types, there's nothing wrong with that. For some people, they're the full answer if you're a light smoker or a social smoker...the tech has advanced enough that it can satisfy well enough for light at-home vaping and last long enough for a night out, etc. PCC's make all the difference for that (personal charging cases).
Obviously going to more advanced units will result in increased performance, but not everyone is ready for that right out of the gate, especially older folks I imagine. There are advantages to going to something that doesn't look like a cig for psychological reasons...but some folks may not take to that as readily and there is a learning curve associated. Pretty easy for the most part with some simple research, but it's just enough that it might put off someone from swapping.
