This is my second kit. My first was from an unknown vendor and it was garbage! I'm considering ordering from nhaler, which is known on ECF. It is the Riva 1100mah kit with new improved manuel button. Comes with, 2 bats, 2 attys, 10 empty cartridges, combo usb/wall charger and carrying case. Its $70. Is it worth the extra mah? And I don't know what drip tips, tanks, and condoms are or what kind of prefilled cartos I should get. Not sure if they even have them. I don't understand the lingo. They have the regular riva 510 kit for $55 and ego kit for $60. I'm confused and don't know what extras I need to be comfortable for a while with the Riva. Or even what kit to get. Compatability is what is also important.
