Can someone explain how a short happens in a 4Nine mod? I'm picking mine up pretty soon, and I've heard that it has a delrin ring to prevent any shorts, but still I'm seeing people say they are getting shorts. Is the battery supposed to make contact with only the 510 conn of the atomizer only? Also since it's a magnetic switch, I heard if it shorts, the magnet will die and just drop? Or does a short kill the battery, or the mod, or both? I'm a bit confused on this subject as well. Thanks !
