I just discovered these things about 3 weeks ago and I really love them. Electric cigarettes are just about the coolest invention for smokers that I have ever seen.
I haven't had a real cigarette or even a minor craving for one since I opened the package when it came in the mail.
I read an article that said the FDA wants to ban them because they found trace amounts of the same kinds of carcinogens that are in cigarettes at 4000 times the dose in only a few of the samples of ecig cartridges they tested. It's really stupid that they say they don't have any reason to regulate cigarettes but they feel like they need to regulate something that has 4000 times less carcinogens than cigarettes.
the first one I bought was from here:
http://endlessvapor.com Which in my opinion is the best one and the shipping was really fast. After making a few purchases I feel confident about recommending this site, I don't endorse anything I am not totally satisfied with.
Then I just had to try a different style so I tried one that was recommended to me, the 510 style which is a three piece design with a separate atomizer. you have to fill the cartridges with the nicotine juice and there is some other minor maintenance. This one is OK, it works and I can get my nicotine fix but I like the flavor & the vapor production that the other one produces better.
I found some pretty good info here:
http://realecig.com if anyone is more curious about it.
I was just wondering if anyone else had an opinion about these devices.
