I agree with Swedishfish, get the Boge 2.0 cartomizers. They are very easy and with the ego type battery you will be set. Just fill with juice and vape. This set up is the least hassle free and easy I have used. I have tried a ton of different stuff over the past year and a half and this has been the most reliable, easy and worry free set up for me. If you have any questions you can pm me anytime and I will be glad to help.
