There is a learning curve, Ill say that right off the bat. I lurked here for 18 months if not more, trying to get a handle on the terms and hardware...till I finally saw a kit I liked and jumped in. That was a couple of weeks ago.
Where I am there arent any
vape stores at all, so it kinda sucks. BUT ..since I got inerwebs I knew to dig in here for info and its helping.
Watch this video, I keep handing it out but wow its made a difference in my vapin' already.

He uses Kanthal wire, the stuff the coil is made of - and makes a new coil, then tests it to see its working, and then sticks cotton in as a wick. The Kanger heads are really tiny but I got a Helping Hands magnifying glass from Harbor Freight - it has a built in LED light too (7 bucks, what a deal). This way I can look super close at what im doing and Ive rebuilt 3 heads so far. Its fun, the flavor and vapor is a lot better than the stock Kanger heads.
My kit I got was a Kangertech evod VV (variable voltage) with 2 Kanger Protank II minis and two batteries. I got 3 5ml bottles of 24mg nicotine too, and vaping that made me feel crispy lol.
My next orders were from Avejuice and Alice in Vapeland, Ave for Boba's Bounty and AiV for a 5 bottle sampler pack - I recently re-ordered some AiV April Moon cuz it was so tasty.
All that stuff in the second order was 18mg nicotine. My last AiV bottle of that April Moon was 12mg nic.
As I keep making better coils, its more efficient at vaporizing the nicotine, I think..so I need less and less.
Ive had cravings but a big honk of vapor and thats over n dealt with.
Another place I got juice from is Ahlusion and their Blueberry-Vanilla is *really* good. I am eager to get some more joose off them in a bit. I am starting to get a collection of small and not so small bottles ha ha.
I also hit up Clark at Nicoticket and he sent 4 bottles: Custards Last Stand (yum, ty Clark), Altered State, Betelguise, and a bonus bottle of Grape Cotton Candy (vaping that one currently). All the stuff in the last go-round of bottles is again 12mg nic juice.
Just dont forget that you have a massive support network here and folks will give you information pretty much at all hours of the day/night. And basically everyone has been through the 'ok im new to this, what do' stage. I am still in that one, I'll admit it.
It gets easier

But you made the first best step, which is deciding you want to cut out tobacco.
