I would have never tried a tank if it wasn't for all the wonderful help and support and Snow's vid. Now I don't know how I lived without one! I just use it at home for now. I guess I'm a closet tankster! So convienient for your favorite flavors! I have a mix of double cherry and cola in my 6ml because it tastes like saspirilla to me. Blackjack berry in my 3.5. Now I need to get more batteries and more 6ml colors! Go gadget girls go!!!!!
