I bought a Tececig electronic cigarette thinking it would help me to quit smoking. At first I was unimpressed and did not use it much. I used it when I could not smoke, indoors and when there was not enough time to smoke. After a few weeks, I was using it more and more, until I was using it more than I smoked! I haven't had a cigarette in weeks and I love the convenience and flavors. My friend Lucy is now using my old unit and I have upgraded to the bigger one.
