What can I say, it is simply a reserve cylinder with additional glass carafe. Granted forced mitzubestellen a carafe really did not like, but now I use more than one bottle, I pretty quickly austrinke the 0.6L and thus always have gekühkt a two carafes. What should also be mentioned, the product box is very sturdy. One reason is that it is used for the exchange shipping. If I have done the first exchange, I'll update the review again.
