the threads were stuffed on the top of my evic- coudnt put anything on it any more!!! not even a carto!!! i had a old evic that didn't work and the vendor said just keep when he sent me the replacement..(the one that now has messed up threads - after a couple years of abuse im not surprised!!!) so rather than buy a new one- pulled the top off the broken one that didn't work and stuck it on the other- now im all good and vapeing without having to buy a new evic!!! yea!!! inside the top plate/cap was really oxidized and corroded- bit scary really- photos don't show up corrosion very well- any way here's the guts of an EVIC!!!
