Worth reading before buying: This type of tank is intended for the user with grater knowledge and experience. Coils used are below 1.0 ohm so that higher Wattage could be used. Before you use please read manual. For Sub ohm tanks we recommend that you do not use liquids with nicotine higher than 6mg / ml and only good quality liquids with 50/50 PG / VG or higher VG. Tanks of this type produce a lot more of vape, which results in a stronger hit to the throat (like higher nicotine in the basic device). Ask if you're not sure ... we don't bite ;-) IMPORTANT! When using a new coil, let the device stand for 5 minutes, so the cotton can be saturated with juice before firing. Do not let the tank become completely empty. Refill the tank to avoid dry burning or damage to the coil.
