I was a smoker of tobacco cigarettes for 48 years, using as much as 2 packs a day. I had quit cold turkey and even hypnosis with no lasting results. My first attempt with the ecigs were purchased directly from China with Chinese juices, unfortunately we purchased a years supply. We still have them, somewhere. I have since tried many different brand and styles. The main problem was not being to replicate the feeling of smoking. After about five years of combined ecigs and cigarettes I finally I was able to find a system that replicated smoking including blowing smoke rings. This was the Joyetch 650mAh battery and tank/atomizer. It finally worked, giving me ample throat hit, flavor and clouds of vapor. The leaking of the tank was a problem and started searching for a better delivery system. While searching Joyetech came out with the Twist batteries. This greatly improved my experience. I then went through the cartos, carto tanks, and finally discovered the Vision Vivi Nova and I’ve never looked back. Total replication of smoking with better flavor, throat hit and tons of vapor. I’ve been off tobacco since 01/07/2012. My heath has greatly improved and I have better taste, smell and lung capacity. My healthcare Dr’s have heartily given their approval. I now use the Joyetech eVic and could not be more happy. I’m using one combination of flavors that satisfy me morning till night. I do experiment with different flavors but only a few puffs. Having the advantage of being able to try many juice flavors has enabled me to help many people switch to this safer alternative to tobacco.
