I just joined the forum last night, and I am glad I'm here. I tried my first e-cig in November, and decided that I could quit smoking with these. I have smoked for over 40 years, tried LOTS of approaches to quitting, nothing worked. Now that I have discovered vapor, I haven't had an analog in over 6 weeks. I first tried disposables, then V-2 cigs in many flavors, now I am using a Silver Bullet with a tank. I love the SB, the tank holds plenty of juice, but the cartos lifespan is disappointing. With some juices, 60/40, it seems to wear out cartos in a couple days. If I use Halo Torque, they seem to last much longer. I am thinking Halo uses a much thinner, higher pg mix. If anyone can share any insight into this, I appreciate it. Also, if anyone knows of a great place to buy tank cartos, let me know. Finally, I am curious about attys and dripping, what is the advantage? Thanks for reading, I know it was kinda long winded.
