I'm understanding the V2 is the same as the V2.1, same body chassis and mold. The only difference is the anion was taken out for the v2.1, and an extra 700mAh (parallel, not inline) battery was added. And that some v2.1 users do have to adjust the center pin (via pencil or long screw) a bit higher. Once you seat your cartomizer/atomizer after that it's a perfect adjustment. I'd consider this "adaptable" in that at least it can move, compared to a soldered fixed position that works or doesn't. Happy accident, if I may say.
