Well it's been over a month for me now without a single cig. I have been vaping with great results. I have tried many different devices with mixed results.
I bought a Kanger Aerotank Mega, like Mike B, and I liked it. I attached it to an itastz MVP mod and found the combination very satisfying. Still, I was curious about the drippers so I got one of those too along with a Smoktech Magneto II mech mod. The dripper vapes like a freight train and consumes e-juice like no tomorrow. Too fast in my opinion as feeding it the juice it can go through will cost alot more dollars than the slow consumption of the Aerotank Mega.
With vaping I have determined that I am a lung hitter, not mouth to lung like smoking a cigarette. The Aerotank Mega has too tight of a draw for me, even with the air control opened all the way up. I then bought an Aspire Nautilus Mini with the new BVC coil. It puts the Aerotank Mega to shame. Sooo much better flavor and a much airier draw when opened all the way up. It also goes through the juice slowly, similar to the consumption of the Aerotank Mega.
The above is just a quick rundown of my vaping story, an example of what someone else might experience.
My whole point here is There are many different ways to vape. Some are expensive and do not work well. Some are cheap and work very well. If you don't find what you like the first time, try a different method. Yes, I have spent $$ in my experimenting, about the same as if I had bought a few cartons of smokes, so the budget hasn't been blown out of proportion. Now that I have found what will work for me, the operating cost will be alot cheaper than cigarettes..... And I haven't had a cigarete in over a month now.
