Here's my review so far on the Revolution V2:
Out of the box: Switch was shipped in the Anion position, dead battery on arrival.
Pass-through: It's been plugged in for 3 hours now, no worky...
When plugged in: the green light is on, when turning it to On and pressing the fire button, lights up red, does nothing.
" " when switching to anion (plugged in) the lights on top go on.
When unplugged: no matter what switch position it's in, no lights, no fire.
Have yet to try it out. Not impressed. I think I'll arrange a return and build a better box.
And FYI, Im aware of the center pin position. This thing doesn't light up regardless of a cart or atty plugged in or not. Not even the anion works.
