before my wife kills me!!!! her zmax I got her came in today. I put in her battery and set her loose. I tested it once to make sure it vaped and it did. She gets it and now it won't do a thing. I have tried looking up error codes and what is coming on her screen I can not find it is"---" that is it. no numbers no letters just that. it will change setting but when you try to take a vape you get that code. the book says nothing and when I tried to Google it I found nothing. if I don't get this thing working she is going to kill me and do the told you so......help me out here. also I thought this thing came with ego threading on it? this one does not have it. Gonna write the people I got it from and check that out with them.
