Hi, new here. I picked up the subox mini c kit for a carry around mod and spilt juice all over 3 times within the first hour!. I haven't seen anything about this so i figured i'd comment. I fully understood the '0' ring assembly as opposed to threaded, as well as how the twist juice adjust function worked. The first time it spilt was do to how much tighter the top was to the tank glass than the base. When i went to top it of, the force it took to remove the top was enough to make the bottom glass pop off, leaving me with a lap full of residual juice. Even though i was sure to keep a firm grasp on the glass while pull/twisting the tip. I then put it in my bag(in what i thought was a pretty secure pocket) and, once again, it disessembled. Third time(being extra careful a this point) I went to adjust the juice flow by twisting. This twist caused the tank to twist off of the coil base, spilling juice on my lap again. I will definitely not be putting this tank in my pocket or bag and carrying it around. That said, the Kanger coils, as well as the user friendly mod(battery sold separate, making it a $50 rig) are the quality you would expect from kangertech. I feel like simply treading either the top, bottom, or both would have made this tank a keeper. But as it is, i will be keeping the mod and replacing the tank soon. It is compact, easy to use and reliable vape. My experience may be different from others'(bad rings or something) but that is the one big 'con' i have.
