My Prometheus arrived and I was very excited to try it out. When I started taking it apart I noticed the air holes and the air flow controller were not cleaned out well. The back end of all the holes have metal flashing attached. It can't just be picked out. I am gonna have to file/sand them. The air flow controller will not spin because of this. There were also a few other areas like the positive pin insulator was not cleaned up well. I have a few other high end devices. kayfun lite, kayfun lite plus, AC-9, AL-1, and some machined tanks and other parts from Tatroe mods. All of these devices came to me in great quality condition. I was just wondering if anyone else has had any issues with grand vapor devices. I expect this type of problem with Chinese devices but not from high end manufactures.
