Just so you know cartos are more convenient than atomizers and cartridges. It is a 2 peice system rather than a 3 piece. An ego kit from Puresmoker has 2 attys (one SR- standard resistance atomizer and one LR-low resistance atomizer)
Cartos come in LR and SR and are cheap and disposable (1.49 each at puresmoker) they can last you a few days or a few weeks. They are good for trying many different flavors. I keep one dedicated for each flavor I
vape. (Some flavors are hard to get out of attys and can make either overpower new juices or make them taste bad. Hence why I use dedicated cartos(notice the CIN on the white cap? it is for Cinnamon))
