My first set up was a Smok 510 kit from Madvapes, actually. It was delivered on a Friday, and I was smoke free by Tuesday.
They were small batteries, and I had to charge them a lot. But I loved them and I loved the kit. I just happened to like both of the juices I randomly picked (Top Vapor Vanilla Tobacco and Blueberry), and that definitely was a big help.
I used that kit exclusively for a couple of months, and then added some egos to the mix and tried a bunch of different clearos and toppers.
3 years later, I am back to vaping with the same type of little 510 atomizer from my original kit, and one of the actual batteries from that kit still works. I occasionally charge it up just for old times.
Thanks for getting me off smokes and this contest, Madvapes!
