I have the Atom from FT (clone)... happen to be using it now. It's my second favorite next to the nemesis. If there's a "real" version of this, it has to be brilliant. The only downside is that if you set it down, it fires. You have to use the lock ring. Not sure the real one has this problem.
Ok, watching a youtube review now. Reviewer says copper contacts. Mine has brass. Reviewer also said the bottom delrin ring compresses which can cause the battery to fire if you tighten down to much. Mine does not have this issue. The delrin piece is taller.
Materials and engraving look much better on the real version.
Hmm... not sure I'm not helping. Watch the youtube vids. =)
