I switched from regular cigarettes to e-cigarette, it was recommended to me by many the Kanger complete and I've not regretted buying, I would recommend this set to get me again at any time. The first filling with liquid indeed went completely in the pants, but you learn from initial errors, and then fills the liquid no longer a center but on the edge. The other operation is simple and straightforward. I have now managed to Non smoking thanks to the electronic cigarette. From time to time I take time even on the e-cigarette but with nicotine-free Liquid.
