I don't feel a carto tank is an "Advanced" user device. Simple, easy to use, easy to maintain and they work great!
As for the Provari or other expensive mod, we try not to push them too much on new vapors for several reasons. The cost is a big turn off to many new vapors, we, and they, don't know if this is even going to work for them so encouraging them to drop the $200 for a kit can actually be discouraging to them.
Many, not all, new vapors don't want a big battery mod to start with, they want something they are used to, like a cig alike.
They have a lot of features that many new vapors aren't sure they need, or know how to use. This can be intimidating to them and we want to make the transition as smooth as we can.
If you feel this is what you want, will use, and are fine spending the money, as many newbies aren't, I wont discourage you at all! I also feel you will save money in the long run vs. buying a bunch of disposable batteries (EGO's are disposable IMO). I've seen several newbies dive right into the pool and be happy, I've seen others try and regret it because it was too confusing for them.
There are plenty of us here to help and support you with which ever way you want to go, good luck!
