The bottle is not bad, it is stable, light and dense. So far so good. However, I am the one with the build quality is not satisfied: the plastic drop had nothing but great ridges. In addition, the Flaschanhals has a coating, this was already clearly scratched me. Ever these thick coating is only in the neck of the bottle and ensures a stupid transition between interior and bottle neck, there certainly is quite fast dirt and bacteria. Last but not least I was the hook still in the "linkage" turn is annoyed because of scratches all the time on the bottle. Overall, one can safely live with the bottle, but I'm a bit disappointed.
