Hi my name is Robin and I live in Texas. Just received my 510 and not sure I have done things correctly. I charged the battery like it said, 8 hours, use for 20 min and charge another hour and should be ready to go. I took off the black mouth piece that came with kit and attached the WHITE mouth piece that had the white stuff in it and started vaping. Does that sound right? So what do I do with the black mouth piece? Is there "stuffing stuff" you can get and add the juice to that to use the black mouth piece? What do I add the different flavors of Juice to? I really need to stop smoking cigs do to heart problems but I feel a little lost. The juice that is in my cartridges is a little strong for me. I am a 3 pack a day smoker and need all the help I can get. Thanks for all feedback. Robin
