Attaching the ConNectar to the battery is a breeze. Separate the three pieces of the ConNectar for the easiest application. Screw the airflow base, or the little piece underneath the plastic straw, directly onto the battery as you would an oil cartridge. Slide the straw mouthpiece over and push it all the way down into place, then screw the Clapton Coil tip on and you now have a fully functioning dab straw in your hand!
