We are 100% satisfied with this decanter! There are several similar carafes, but with this Ausgussystem WMF has really lifted from the competitors. In the shop we have had many such jugs in hand and the WMF decanter was the clear winner .. For all other there was the simple wobble either rattling noises or you could easily open the lock, it would have done even a liter of water .. The metal balls also serve their purpose so well that we have already used for cleaning the kettle :) I recommend to all who are looking for a chic but also proper functional water carafe!
