OP, I feel ya. I spent about a year screwing around trying to get things working for me, until I finally got fed up and went back to full time cigarette use. I sold all of my Protanks, Evods, egos, cig-a-likes, chargers, everything, and didn't bother looking back . . . until recently. The problem with smoking is we all know it's a road to nowhere, or at least an early grave. So, what are the choices, I asked myself, to quit cold turkey? Well, as noble and pure as cold turkey quitting may be, I just wasn't getting anywhere that way--wasn't even starting. The very thought would make me smoke even more. At the same time, I think smoking is such a PITA with the constant cravings, restrictions everywhere, and the general erosion of my health. So, I thought what's the alternative? To smoke until death? I'm sure we both agree that's not really what we want to do to ourselves.
So, then I come back to ECF after a hiatus of a few months, and I read member after member that used to smoke 30-40-50 years, who's life has been wildly improved by switching over to vapor. Some members have even moved beyond nicotine use and no longer need to frequently vape, if at all. And all of this with very little effort compared to conventional way to quit smoking. I want to capture some of this thunder!
So, now I have a Vision Spinner, a carto tank, and a 15ml bottle of RY4 on their way right now. I have high hopes that the VV battery and carto tank will prove to be reliable enough to get me off the analogs, finally. I chose this specific gear based on my previous experience with BCC tanks and straight voltage batteries, as well as advice given on ECF regarding carto tanks.
So, what I'm trying to say is, if you are frustrated, then just put it all on a shelf and forget about it for a while, let the negative emotions fade before trying to get things working again. In the meantime, maybe work on stabilizing your cigarette use back to your normal level. Being frustrated and angry at your gear, and also panicking because your still smoking, will guarantee that you smoke more than before, and then you'll feel even worse. Perhaps, view tinkering with your vape gear as a sort of puzzle that you want to solve, rather than as a quit smoking device. I think if you remove your negative emotions, then things will start to get easier.
