i dont understand this new tank body in the slightest. all it is is the plastic tube, with metal glued on the outside. what in the world would be the purpose of that?? if it were an all metal tube with a tiny plastic window, it would make slightly more sense but this design functionality is perplexing. maybe the metal is to prevent the tank from breaking due to a drop. but thats pretty unnecessary as these plastic tubes ar enot likely to break from dropping. youre more likely to break the 510 connector.
but thats all i can come up with because its certainly not for using cinnamon, citrus, or any other jucie that would cause a tank to leach. it will still leach, just behind the metal. a "neat leach", if you will. maybe if someone is experienceing severe leaching to the point where the tank is cracking, it might help. but even then, the juice will still seep out, once the crack reaches the window. or perhaps before then if the metal is not glued airtight to the plastic. very weird concept IMO.
