I've had numerous people ask me how E-cigarettes work. They're pretty nifty! ..But what happens when the cartridge stops giving?
Well then it's time to get a new cartridge refill!
Remove (unscrew it) the empty cartridge from the E-cigarette.
Get the new cartridge refill and screw it on.
And there ya go! Your E-cigarette cartridge refill replaced within just a few seconds!
