I just don't get what these offer over getting a box of wine and just taking the bag out of it, you get good bagged wines now that are properly shelf stable so not sure what the advantage would be of decanting a bottle into one of these unless I very specifically required that bottle. Are there parts of the world where bag wine is so terrible you need to risk decanting your bottles into this? It just seems a product trying to solve a problem that was solved a while ago.
