I have literally had this thing for over a week now and have had NOTHING but problems with it. My husband also has one, but his is just fine. I've taken it to two different e-cig stores in my town and neither of them can exactly figure out what was wrong with it. It's not only leaking out of the air holes, it's spitting liquid into my mouth, and sometimes it just refuses to work at all. I've replaced the coil 3 times with it, and it works for literally an hour and then it starts giving me the same issues, and I know it's a legit Nautilus tank (I've already authenticated it). I feel like I've wasted $30 on this.
