It's the only e-cig I use. I use it with boge cartomizers though, never did use the atty+cart that came with the kit. I like the ego-t on it, but I tend to go through much more liquid than I do with the boge cartos. Good e-cig though, I don't think you'll find anybody with any complaints for what it is. You'll hear a lot of "that old crappy thing is useless, get a
mod!!!". But for what it is, you'll be happy with it.
