I knew about it years ago. Unfortunately, what I knew about it wasn't all that great. Those I know who tried it wound up back on analogs fairly quickly back then. Plus, they were super expensive. I never had the starting out money for it. Now, in 2013, the price for a pack of Marlboro's in NYC is $12 per pack. Could be up to $14 depending on where you buy them. An ego type battery and clearomizer cost me $15. A bottle of 10ml e liquid cost me $5 something and lasts me about five days. So, that's $20 spent where it would have cost me $60 in cigarettes. I win financially now. It didn't seem I would years ago, when I first heard of them. And it seems that lately there has been a great deal of advancement in the industry, with much more choice and options in general. It all seems doable now, where back then it just wasn't.
