Welcome the ECF gjshaw! The best ecig is the one in your hand

Great that you have an eGo on the way. I have 3 of them and they perform flawlessly. In time you will learn the best types of set up using your eGo batteries. Many kits come with cartridges and atomizers. Some come with cartomizers (these are the cartridge and atomizer in one unit). Some come with tanks (tanks vary in all different shapes and sizes).
As time goes, you will quickly learn the differences affording you the knowledge to enhance your
vaping hardware. There will be many recommendations along the way which some you'll try and like and others may not be suited for your tastes. In any case, hang in there. We all pull for one another as we fight the same enemy. Welcome again!
