I started with a 808 kit then bought a couple of 510 kits. Then came the ego 1000 pass-through now I am on to a Lava Tube and a revolution V2.1 and waiting for my indulgence kit to arrive. For me the 808 kit was a waste but it was my first e-cig so it has a special place in my heart. My recommendation to any one just starting out is to buy a riva 650 kit and Kanger 510 cartomizers. If you choose not to stay with vaping you will not regret the price of the kit and if you are like the rest of us these are a very solid unit that work great.
