I don't know. Since the ones that Rob is worried about are a sizing issue, that would be difficult for us to see as they are very small. As to the atomizers, cartomizers and adapters that that have caused shorts due to bad gaskets, I am not sure they are visible to the naked eye either. I do know, however that when this center post on adapters sticks out farther than the
threaded body, that is a sure fire way of knowing that it could cause your
mod to short. Should be something to keep an eye on with your atomizers & cartomizers as well. I'll let you know if I hear of any other way of knowing.
