The makers of the "GOD MOD" have now come up with a new mechanical box mod called the Kung Fu. From what I can see its going to have the standard dual 18650 design - powerful magnets to hold the backplate in place, an upgraded 510 connector, and nice switch. The wires going to the 510 connector look extremely thick. The fit and finish look very clean.
Even if this mod sucks - It has a picture of Bruce Lee on it - which makes it epic.
I'll be getting one these as soon as they pop.
