I'm excited too! Especially since they'll take 18650 batteries (so the vendor has confirmed)! I have a pre-order in. From what I understand the Tmax should ship from Sigelei today and the orders should be in our hands in the next couple of weeks!!
It's a metal box mod with the Zmax chip and menu....VV/VW ohm checker...the works!
The silver one is the "revised" version that uses the 18650...which you can see next to it.
