Perhaps its just the way it is. I really love these 2 products. The only drawback I've found is when I put them away in my little stash bag, they often will fall over on their sides and then liquid comes out. I hate wasting liquid. When the juice gets up to the top metal ring (the one you screw off to fill) it seems to seep out. If there were a special bag to store these in, I would buy one. Say with little pockets that would keep them in place. I'll try to put a piece of tape around the top to see if that does anything. Just wondering how others are doing with this. Perhaps Gotvapes can take this into account when they do what they do to get upgrades. Maybe the manufacturers can put a seal around the top or something.
