I'm not sure what to do with my Ego kit. I have switched from Blu (only had battery, flavored cartridges, and chargers). This has so much, that I am truly confused. I don't know what to put my juice in. Boy!!! am I stupid. Just a female baby boomer that has smoked 40 years, and it's time to QUIT! Please help. Not up on all this electronic tech. THX!
