I had been flirting with vaping since the summertime - I had bought the nJoy setup at 7-11 stores, and was using them part of the time. Then the weekend of November 12 I started vaping (I had had gotten pneumonia the week before, so now I knew I had to get serious with this). I bought a starter kit from Phantom Vapors - I don't even know how I found them on line, but it's sort of like a KR808, but the battery has a female fitting and the cartos have the male threads. I bought their refill kit with three different tobacco-like flavors (I smoked Parliament analogs), and have been using those flavors plus their French Vanilla.
I was getting over the pneumonia, so my breathing was already compromised. After about 2 weeks on those, I found myvaporstore and their KR808D-1. I wanted to try a manual battery, so I sent for their starter kit and swithced over because I like it better. I also bought their RY4 juice.
I noticed that the myvaporstore.com KR808 have a much easier draw than the first kit I had (it had auto batteries). I thought the shortness of breath might have to do with drawing so hard on the auto battery unit, but it didnt make a difference when I switched over.
I'm making an appointment with my pulmonary doctor this week. It's a drag that I'm doing so well with this, but not feelling better. Thanks so much, swedishfish, for your input - I'm going to order some of that Halo juice.
