I got my e-cig 2 days ago and have some questions.I wish I had found this place before buying so I could get experienced advice on brands and such. Anyway, I ended up buying a mini cigarette DE-5082. I don't see that listed anywhere on here but that's what the user guide calls it. It came with 2 batteries, a charger, 6 cartridges(2-high, 2-med, 2-low, and 2-no nic)and an atomizing unit. Is anyone familiar with this? So far things have been going ok but it seems the cartridges run out pretty fast. I was thinking perhaps that dry out some before they ever reach their destination. I thought maybe I would get better vaping if I bought some refill liquid. Any suggestions? Also they're tasting a little sweet to my taste and since I'm a non-menthol smoker I would prefer no sweetness. Also, which blank cartridges can I buy to fit this model if I plan to fill them myself? Thanks
