I found out through a classmate during a discussion about the new smoking ban on campus. He has a Blu and recommended them so I ordered their kit. Since it was going to take them a while to send it out I went to my local smoke shop and got their cheapie E-lites pack for around $25. That got me off analogs, but then when I was trying to figure out how to refill my Blu carts I found ECF. Since the batt life on the Blu wasn't cutting it for me I went out and ordered a 510 after reaserching it a bit on here, and have been a happy vaper every since. I'm even starting to convert a lot of my friends who smoke to come over to the vaping side, lol
