I vape an eGo with 510 cartos. I've only had it a few weeks and it's great except for one cartomizer. It has virtually NO throat hit and the vapor is a lot less than the others using the same juice. Cartomizers are pretty cheap, I know, but I was just wondering what was wrong with it in case I run across the same thing in the future, I might be able to fix it. Any ideas or things I should try?
