This line of RTAs are great. I have the mini, which i really enjoyed, so I decided to go ahead with the V2 for a little more power on my bigger mods. No leaking, though I am an experienced RTA user, and tons of flavor. This is a bottom airflow tank so the flavor is better than top airflow ie Zues or Dead Rabbit, so the potential to leak is there if you don't wick it correctly. Easy to build on. The RTA is a little loud but it's not crazy loud. The draw is smooth and it's so easy to build on. Definitely recommend this to even novice RTA users. Just remember comb out the wicks a bit but leave enough cotton to loosely for in the wicks slots and you shouldn't have any leaking.
