I have to say the best Ecig is the one that works the best for you, size, shape, looks, features, its all up to the user, one might like X while others say their nothing but problems. If your not smoking cancer sticks, then whatever you have that keeps you off them is the best, and of course as people grow with more knowledge and want the cooler stuff, things change and the industry grows. But always remember that you get what you pay for, cheaper isn't always better, but thats just my opinion.......
