Received my ECigarettes Starter Kits on Jan 12Th, 2013. Four days and four real cigarettes later and I threw the real cigarettes away. I really love this product. Very convenient no more looking for lighters, no more smoke smell, no more dangerous chemicals. Also seems to be less expensive than regular cigarettes. I would definitely recommend. My wife will be purchasing one next. Before this e-cig a pack would last about a day and a half so if you smoke heavier it may be a little more of an adjustment but I have not had any bad cravings or withdrawals. I recommend the travel charger and to start the highest level of nicotine.
