The Eciggity one is a normal V2 in 350 mode (in 350 mode, all that should be visible is copper bottom ring/cap).
On Grand Vapors official site, there is no mention of one with SS tubes rather than brass. Not saying that's definitely a clone, but if not, I think they've changed out the tubes or something. The reasoning for why they would do that escapes me, but eh...
This is one of the many reasons counterfeiting/cloning is bad.
