So i ordered a copper mod and some 510 batts and such from rick at vapor alley. The hex is awsome but the 510 batts were listed wrong on the site. I dropped rick an email when the package arrived and he sent me a 6ml tank and box of punched dual coil cartos in exchange for the batts. The dct makes the hex the vaping machine it was intended to be and i definately reccomend this setup to anyone who ones a copper mod. Needless to say i will be shopping there from here on out. They are definately one of the good ones.
