It's alright, not amazing. CCI tends to do this weird thing with the AFC to where the two different sized airflows overlap. It probably won't be an issue for most people, I just kinda OCD on the fact that you can't completely cut airflow off. Not that you would want to, but you should technically be able to.
Anyhow, wicking is a little finicky. If you had one of the old Mutanks, the build deck is similar. You can get dry hits or leaks easily, but once you get the wicking right it vapes good. Flavor is good, vapor production is great. Build quality is the best yet from CCI that I've seen.
I probably sound down on it but I'm not. It's certainly a useable
tank. I got the blue and the color and finish is awesome. I love the look of it. But you can get a better vape, or at least as good for less money. If you've got some disposable $ than you probably won't regret the purchase. If you're saving up for a tank I would probably pass on this one.
