I bought the atomo from vape royalty a while back.  I really like its looks and I have had zero misfire problems out of it.  I kept a regular russian on it for a while, now my nimbus stays on it for when I am in the mood to use a dripper.  I have one russian on a magneto, which I love because the switch has a lock on it, the atomo does not.  I am skeptical about carrying it out and in my pocket with only a recessed button, but the tines I have carried it, I could not tell if it ever fired with out my doing so.  As far as build quality of the atomo clone is concerned, its machined well and doesnt feel cheap.  I would buy again if something were to happen to the one I have now.  I am even contemplating buying a real atomo, but from what I can tell, the clone from vape royalty is pretty damn close.
