I just purchased a 78mm battery, and I have to say, I'm having a lot of trouble with it. I fully charged the bloog battery before using it and I am noticing that I have to suck extremely hard on the cartomizer to engage the switch, almost to the point where I'm getting a headrush/headache from having to pull so hard! And even when it does engage, I have to suck even harder to keep it engaged! The rest of the time, if just taking a pull with the normal exertion I use (and am used to having to take), the switch does not engage whatsoever and I'm just inhaling air. I'm assuming maybe there's something wrong with the airflow/holes/threading in this particluar battery I've tried this with several of the bloog RY4 cartomizers, as well as with several non-bloog cartomizers to troubleshoot. Additionaly, I've tried the same several bloog cartomizers on non-bloog auto
batteries for comparison, and am having no problems, so it certainly isn't the cartomizers. Has anyone else had this problem? Or perhaps I received a partially functioning battery? I'm hoping that's the case, as I really would like this to work!
