I've has two eGo One tanks, and both produced copious amounts of seemingly wet vapor. Both also would leak juice out through the air flow holes, rendering both eGo One tanks impossible for me to carry in my pocket while going about my day. I tried all different types of coils, even wound my own coils and wicks, but no joy.
I have two Nautilus Minis running 1.8 Ohm coils that I use on an iStick 30W. Although they produce less vapor than the eGo One tanks, both the Minis are solid performers that never once leaked any juice on me (unless I made an obvious mistake). Occasional gurgles and condensation buildup are easily resolved, too. With the eGo One, just 10 minutes of vaping would lead to condensed juice flowing out of the air flow holes. So, yeah, while the Mini may be a step backward, it just plain works without a bunch of issues.
