So far in the past two days I've had a major flooded carto when I put it in a tank.. lost over 3 mls of Boba's in the process. Then I filled another carto with just one hole and it did fine until today it started flooding too, which I thought was strange since it was all vg juice. Then I put some strawberry shortcake in a brand new Stardust v2 and all I got was air, no vapor, no crackle, no nothing. I am having no luck with my equipment, I'm losing juice, and I feel like I'm just throwing money in an open pit. I love vaping but would really like to find something that works consistently and so far I've not found it. I'm very frustrated and close to buying a pack of nasties. I am tired of fiddling with equipment to get it to work right. Am I the only one that gets irritated and frustrated like this and what have you found that works consistently? Thanks for any help!!8-o
