My Zeus and some tanks arrived in the mail yesterday, what a difference! Lots and lots of vapor! I'm really happy I decided to take the plunge and upgrade from the smaller batteries. My DH was picking on me for vaping out of this large contraption, until he tried it.... He just asked for a Zeus for Christmas!!
If anyone out there is deliberating about whether to go big or not, IMHO, the answer is a resounding yes. I'm thinking I will ask for a DAV from Santa as I've heard some juices scorch at a higher voltage.
I'm also very happy with the tanks because I don't have to worry about burning cartos.
Thanks all for your advice and help on my journey thus far!
