Hi guys, So as i've been getting more and more into this world, I stumbled upon the EGo clearomizers (stardust type) at hoosier's place and I love em. So easy to use. My issue is, once I had it for about 3 days, it started sporadically dropping out sometimes and eventually stopped working entirely on one of my batteries only. The other it does just fine. It's like the power connection isn't making properly on the one i've used more. Funny thing is, regular cartos still work on the one that the stardust does not. Any ideas as to why this would happen and how I can fix? Thanks!
