I was a might be afraid of that. I detest burnt fill, which is why I have loved the cartos and ditched the attys cause direct drip is a pain, though I direct drip cartos alot. I only ordered two packs so if they turn out to be so so I will live.
What I did notice that works well is that noalox stuff applied to the battery end thread. Seemed to give a bit more oomph. But wash you finger good before hitting the switch or it will feel funny! LOL! Not sure what that sticky grease is made with but I feel like I get a better connection. Might be in my brain though.
Still have a bit of June allowance left so I'll probably grabbed some more megas from Drew towards the end of the month. I know it is good to try new things but chucks and mega cartos have not let me down yet so I really outta quit while I am ahead but then again, it's what keeps
vaping interesting, which keeps me from even taking one hit off an analog.
