Note: You must "prime” a new coil prior to the first use. Simply drip 4-5 drops of e-liquid directly onto the center wicking material of the coil after the coil has been attached to the base. Fill tank with e-Liquid, then reassemble. Look for air bubbles coming from the coil when the filled tank is turned upright. This indicates that the liquid is saturating the wicking material, and will prevent getting a burnt taste.
