I'm not sure if it's a color related. After messing around for 2 weeks with the Zeus x it is FINALY not flooding anymore, and I have been able to vape on it for 2 days now. It really just wants a lot of cotton and wheter it works or not I now close the afc when filling.What issues would that be? I'm thinking of getting a black one and would like to know if there are issues with it. Don't know how a color difference could be an issue, but please clarify or link to wherever you read it.
