Is there much chance of getting a mouthful of
juice with these?
I have, but that was due to my own noobness, not filling carts correctly or cleaning properly. I've found that it helps when you fill the cart to pop the inner cart out, wipe the outside of it and run a Qtip gently around the inside of the outer cart. Otherwise you can end up in
juice city.
When they are carried around are they "messy" do they leak?
Not at all. There's nothing messy about the Evo really, it's a nice small cig. As I wrote in a review on their board here, to me it's fairly dummy proof. I haven't wrecked a piece of it yet. I drain the attys every so often and have cleaned one pretty extensively and again nothing has died on me yet (though obviously it's only been about 2 weeks).
I will probably not be refilling at first anyway. Are the carts messy to install or use?
No, this is a very easy to use e-cig imo. What's nice about the carts you get with an Evo is they have a larger inner cart than typical 401s.
Even if you don't think you'll be refilling, order some extra juice as you'll want to top off sometimes or drip a little on the wick (making sure it soaks in!) for a little extra hit.
Definitely watch the videos they link on the Intellicig USA site, they're a big help. Also check out the Intellicig board here for more info.
