It was when I bought this same kit that I realized I could really stop smoking. I did trade the atomizers in for some ego-t atomizers and tanks. The tanks are so much cleaner to fill, and you don't have to worry about that polyfil stuff. I watched a lot of youtube videos. My favorite is Scott Bonner (Igetcha69). They are very informative. Good luck with your Egos, I know you will love them!
