I've been dabbling with non-smoking forms of nicotine delivery for a while now. I've designed a few vaporizer pipes that I've fabricated myself and while all of them worked very well, each one had significant drawbacks. I still found it easier and much more convenient to just smoke a cigarette and although I never went as far as to buy my own, I still got my hands on one every few days. I've found that I have a fairly high tolerance for nicotine since vaporizing tobacco is significantly more efficient than smoking it and cigarettes never really cut it for me.
I've had my dse-901 for a little less than a week now and I absolutely love it. I've switched solely to my e-cig and even gave away my latest vape pipe to a friend that could put it to better use. Although my nicotine intake over the course of a day is higher now, I feel much more satisfied by my e-cig than any of my vaporizers. I'm not sure if it's the ease of use or the taste that I enjoy so much, but it's just more fulfilling for me. I also love the form factor of it. I got the 36mg cigar flavor from puresmoker.com and it's absolutely yummy for lack of a better word. I'd like to add some different flavors to it, but I'll have to wait until my next paycheck before I can play with flavors. I think the cigar flavor makes a great base flavor as it tastes very clean and smooth to me, and also tastes fairly close to tobacco.
