I've been vaping for over a year and still can't give up the analogs. I have had 4 different models and still it hasn't worked. I just bought a magma e-cig kit and I think that might work. The PCC seems to might make a difference for me. At work the other e-cigs I had didn't cut it and I think it is because it was to much of a pain to carry chargers around so I gave up. I do hope this works, if anyone else have had the same problems I've had please let me know.
