Hubby n I struggled till the tech caught up to what we needed. No leaking, burning or cartos that simply fell apart. Finally got hold of some t3s a couple mo ago and quiting just happened.
Here's something interesting.... There have been reports that people quit smoking without even intending to quit once they tried vaping. I am one of those people. The day I started vaping, I finished the pack of smokes I had open, and never picked one up again. That was about 10 months ago.
I LIKED smoking, and had no intention whatsoever of quitting.
YMMV
