Just my words of caution, if you are in an area where your temps can get over 85°F, there's a very high chance of leaks. At least that's been my experience with every clearomizer I've used. I've never used the Nautilus Mini before, but it looks very similar to the AeroTank Mini. The Sapphires from GotVapes.com leak the least of all I've ever used (only 2 occasions, and they were small). However, the hit is so restrictive on them, and I find the flavor isn't nearly as nice as other clearomizers I've tried.
There are things you can do to try and minimize leaks (storing upside down, thicker juice, etc), but it never seemed to help me much. When I stored mine upside down, I didn't get leaks into the battery anymore...it started to leak out the drip tip! Granted not as much, since basically whatever was absorbed by the wick would start to leak down, instead of the whole tank. But a leak is a leak.
Keep in mind, my leaks are primarily heat induced. If you live in a cooler climate, this might not be much of an issue for you.
I did have a Kanger EVOD leak a hefty amount in my pocket at the Tool concert though. Still have a stain on my boxers and jeans I wore that day. I can always tell my Tool boxers because of it
I'm switching to a Kayfun 3.1 to see if that controls my leaking situation. It's been delivered, I'm just stuck out of town for the next week before I can test it out.
If using some canna-juice wasn't so damn stealthy and convenient, I would have given up long ago!
