    Warning: Please ensure to properly prime each coil and pod before you use them. Always use proper precautions and handling. If the coils has a sub-ohm resistance, sufficient technical knowledge and understanding is required on the use of batteries, mods, and kits that can handle Sub-Ohm coils. If you are unsure whether you are familiar or not on particular products and/or set-ups, please do not use. Never use short or flat 510 connections on any hybrid/hybrid style devices. There is always an inherent risk when using any rechargeable batteries at any time and under any circumstances. Please ensure that you have great knowledge on all rechargeable batteries before you use them with your vaping device. Always charge batteries at the clean and fire-proof surface. Never leave charging batteries or vape devices unattended. If batteries are visibly damaged, do not use. Please have sufficient understanding of the batteries/chargers and any rechargeable cells you are using and how to care for them properly. Always store, keep and transport the rechargeable cells in a safe, non-conductive container in a controlled environment whenever possible. Rechargeable cells are very sensitive to charging characteristics and may explode or burn if mishandled.
