The threads on the blanks I bought don't match up with the battery threads. Has anyone else noticed this? They screw on,but are loose,and the cartomizer is out of whack unless you tighten the hell out of it. At this point air flow is a problem. This completely bums me out because I bought a dozen boxes. This problem should of been caught before they were sold to me. These are the older style cartomizers in red,green,and yellow.
