I have tried both the e stick and the e pen. The stick was great for cutting down on my smoking I did try to quit using the e stick but I didn't have the confidence that it was giving me enough nicotine to quit cigarettes altogether. Then I tried the e pen I found that the e pen straight away looked and felt more powerful and thus gave me more confidence that it was giving me enough nicotine to quit the cigarettes. I found that I was able to come off cigarettes in two days. When I was using the e pen I felt I had complete control of my nicotine intake because of the way it works. Whereas when I was using the e stick it felt like the e stick was in control of my nicotine intake. To sum up I think the e stick is great for cutting down in preparation for quiting smoking and is also very handy if your always on the move. But I think the e pen is ideal for quiting because of the way it looks and feels and also because of the way it lets you feel more in control. I haven't had a cigarette for 4 months thanks to the e pen and of course a little will power.
