Yes you may of course call me Lisa!
Bear with me as this will be long winded! :0) But learn from my mistakes lol
You do need a kit with two batteries, one to be used and one on charge, these batteries are really good though and will last a couple of days per charge. And I use mine a lot!
I bought this to start with...

And it's good but you then need some of these... as opposed to the cartridges it comes with...

They attach to the Ego battery and are so much easier to fill with the e-juice/liquid, and give you a better and cleaner throat 'hit'. The amount you fill them with lasts longer too, so you only have to re-fill once a day [depending on how mush you vape]
Then all you need are your liquids! I have worked my my through various tobacco and fruit flavours and now 'vape' menthol. This really is of course a personal choice.
Loads to choose from though.....

For me it was the best thing I ever did in regards to my health and please do feel free to ask anything else you need to know :0)
