The bottle comes in handy when you have loved to drink a lot, but do not always want to have tasteless water. She keeps close to me, they can therefore, for example, in the backpack without transport that it has completely soaked at the end. Do they even until now washed in the dishwasher always what she has endured (in ~ 2 months) without problems.
Once it has fallen to my friend from the normal rate down because her backpack was not properly closed. This has the bottle though endured without being broken, but this worked out and the floor was of course completely wet. Prefer still no star off because I prefer the bottle to go as it breaks!
