I just started vaping about 3 weeks ago, I have the ego-c battery with a dct carto tank. I started with the vision v2 but it was really hard for me to pull on and get the hit I was looking for. Once I switched I never want to go back. However, I've gone through like 5 cartos since I've started, they keep burning out, dont know what if anything I'm doing wrong but Iv have ones go out after just a day. Any advise? Also anyone recommend a good model with a decent amount of capacity.Thanks
