A pity, because I did not found the bottle initially bad. The bottle smells and tastes like no Plastic and can be built well apart and clean, but unfortunately does not the most important. While you can drink from the bottle, but it is every time you open the danger that one person in his environment with the contents of the bottle downright "shoots" himself or. I rarely managed to open the bottle and drink from it without me there to make previously wet. It is also almost the same whether one uses carbonated or non-carbonated drinks that problem is sometimes more or less available. The opening of the bottle with one hand is really great, but the device fast as fast high that it catapulted the content, which is in the drinking tube to the outside. That might be funny, if you want to give a water hammer and no guns, but did not when you take the bottle at work and one (no kidding) meter wide fountain splashing wet people in his environment. I am sorry, but the bottle is only in our closet because it is just unusable.
