I, too, started with Green Smoke. And they DID cut my smoking way down. I did like the flavor, as well. However, the cartomizers do not nearly last as long as they state on the website, and it gets very expensive to replace them.
I quickly moved on to an ego passthrough battery with Boge LR cartos, and DIY
e-liquid, which has been what I've been
vaping for the last month and a half. I stopped smoking completely with the ego combo.
After tons of research, though, and tons of time here on the forums, I have made a very well-educated decision to go ahead and get the Provari. I will be using the boge 3.0 ohm SR cartos and DC
tanks with the Provari, when it arrives today, and I'll continue using the ego combo as a backup.
If price is not an option, then I would highly recommend a big battery, variable voltage mod, like the Buzz Pro, Provari, or VMod XL (box mod). Battery life, vapor production, and flavor are a HUGE considerations; size, asthetics, button placement, and feel are personal preferences. We can not, and should not, tell you what your preferences may be. That is your decision and your decision alone. We can give you our opinions, based on our experiences and our own personal preferences, but it's up to you to use these as a foundation, and decide what would fit your own personal needs and wants.
