Okay. I know they screw into the battery. I guess I'll have to research where I can another kit in the $30 range. The one I had stayed charged forever and still wasn't dead months after use...I just had the misfortune to lose the darn thing.
If you image search vapor ultra you'll see a kit that has a silver case, 2 cartridges, and a fully assembled cig. Just to clarify so when I order stuff I'm not messing up.
