Honestly, you won't find something "just like" a cigarette.
But literally millions of people now have tried, and found something they liked BETTER.
So YES - you can find an ecig that satisfies, and quit smoking.
It's not really simple though - because different people like different things - and what you like may change over time too.
To quit, you may want a "tight draw" - where you suck kindof hard like a cig. But many move on to "more airflow" - where you inhale more gently, and probably get more vapor.
Flavor is mysterious as well. A LOT of vapers START by looking for a tobacco vape, then are suprised themselves when they quit smoking after finding something like "Chocolate Raspberry" or "Vanilla Cream Donut". LOL.
If you CAN, find a vape shop that will let you try a few devices. Some stores are full of idiots, but some can be very helpful. Don't let them tell you something is "the best" if they haven't first asked about your preference, and let you try some stuff.
Here is a decent selection of popular, flexible devices that might be good for a "new vaper"...
Mostly "big brands" where you'll be able to find coils, switch to other tanks if needed, etc - companies like Kanger, Innokin, eLeaf. And yes - MOST of the good gear is shaped like a box. There are a few decent starter "tubes" if you insist - but often people outgrow those.
Good luck!!
I have loved and hated smoking...it's been my master for long enough. I tried a couple of e cigs which were not robust and broke, the complete turn off was having a coil burn out while I was taking a drag which was unpleasant and led me to loose confidence in vaping. I need your help in selecting the right vaping kit. I need a similar effect to Marlboro lights? Can that be done?
