Do any of the other clearo tanks screw together like the viv nova ? I kind of like the look of the ego styled ones such as the kangers and the stardusts. I tried the stardusts when they first came and liked them except for one thing. When I would put them in my pocket they would get stressed from me moving and twisting and the plastic tube would separate from the base leaking all the juice into my pocket. I now use the vivi novas and since they screw together I no longer have this problem. However I'm interested in trying others just for varieties sake but don't want to end up with juicy pockets.
