I vaped almost a year on 808 models, starting out with a V2 starter kit. Not a bad kit, as far as "cig-a-likes" go, but I found the Halo cartomizers were absolutely excellent. Easy to fill, and really consistent, they perform rather well. I fell off the wagon for a while, and just picked up vaping again recently.
I stopped at a local e-cig shop, since they opened recently and I was curious. Tried some of their flavors on an Ego setup, and was impressed. Eagerly awaiting my Halo Triton tank system, which should be here tomorrow. As I said before, I was very pleased with their cartos, and the Triton seems to be a good product; read a lot of good things about it. As a Ego-style setup with 808 threading, it'll limit my choices, but I think given Halo's reliability and consistency, it won't be a problem.
