I'm not actually sure lol I kinda went in blind. It says eGo AI0 on the side like I said completely new to this. The guy at the shop suggested it.
Whoo hoo.

You got a great starter e-cig.
It's the only one I give to people (to try) these days. Also, it beats spending $100 on an outdated pen type (worth $19.99) from the greedy brands.
Joyetech, Eleaf, Kanger are Chinese makes (or assemblies in some cases)
Halo, Vaporfi and V2 are brands.
The difference is they take Joyetech, Eleaf and Kanger products, make up some dubious (and sometimes immoral) marketing strategy and run off with your money. Halo do it in a small way which hardly matters but others are just unstoppable in their greed and determination to convince the internet they are superior. It's a very silly game which the community tolerates.
I, on the other hand see through the see-through behavior.
