I am so beyond frustrated with mine that I got from Got Vapes, the bottom coils!!! I dunno what the hell I am doing wrong but I'm ready to cry!! When I first got them I loved them, they were working great! I had refilled one about 4 times and I wasnt getting as much vapor as I was at first so I watched the GotVapes video and cleaned them. I decided to clean all 4 that I have had different juices in because that I could make them all like new. Well now none of them work right and I have no idea why!! I have the plugs in the right way and pushed down tightly and two of them are leaking still, and the other one ive managed to get it working but the vapor production is really weak. I have posted about my experience in the GotVapes forum and people have tried to help me and still they arent working!!!
