I do not want large-evaluate the bottle itself, as I have sent back, this has already happened and I share the here. But very misleading, the term "fixed-closing" when the bottle, once filled with soda (thank goodness it was not coke) initially is tight, but then suddenly (for example in the trunk of the car) "blows up" and a three-quarter liter liquid (in selfsame) pours! In the bottle holder, however, it fits really well. Recommended is a model in plastic, otherwise the Geklicker and Geklacker the bottle is very annoying vibration.
