I have a 510, pulled the cartridge off and some of the fibers is that the right term?) in the cart were sticking out and got stuck on the steel wick(right term?) in the atomizer, I pulled what I could off with skinny tweezers, it smelled a little funky at first but seemed to be working Ok afterwards,, did I do any damage? anyone else have this problem? I now push the fiber stuff into the cartridge so its not sticking out and trim it,, moving onto cartomizers very soon,,hear they are cool,thanks for your help as always
