With all the regs that may be coming,, get a replaceable battery mod.
The Vamo's are fine as well,, get either the v3 or v5
And they have the eGo and 510 built in.
But ultimately the Provari and don't look back.
They are simple to use. and plenty of places have the adapters.
Check MadVapes for one.
Also, learn how to build coils and stuff and get an Hcigar Kayfun 3.1 ES
they are easy to build after a little practice and a lot of info out there to help
They are, imo, one of the best tanks around.
Very efficient delivery system.
You can also look at the Mechanical's, there isn't much to them, straight full power.
Personally, with all the deeming reg's and the hard core legislation on bans attempting to be pushed through, I should be set.
I have a whole lot of NIC in my freezer.
A White Provari Mini
2 x Hcigar Kayfun 3.1's
A lot of Vivi Nova Mini's and heads that I know how to rebuild.
An iGo-L that works fantastic when setup properly.
2 Vamo's a v2.5 and a v3
a couple Vision Twists.
The ANTZ can kiss it.
