Some have been here reported the problem with broken glass when closing.
Since the majority of recessions is positive, but I assumed that this problem from improper handling (to turn solid, strong vibrations etc.) results.
As the glass carafes well packaged arrived with me, I was initially relieved by the robust.
However, after only four weeks, I must unfortunately after pouring that a piece was broken by closing out and was in my glass. Fortunately, I had noticed this even before drinking.
The carafe was previously neither initiated nor anywhere I had turned off the closure overtighten.
My advice, therefore, in any case, this before drinking to check the closure of harm.
The negative recession I write because I do not go out of a particular case but in my opinion there is a design flaw.
In reusable bottles of mineral water this problem has never occurred to me, even though these also have a screw cap.
Edit: Since the complaint was carried out fast, friendly and uncomplicated I forgive three star and hope that the problem with the defective screw caps of SodaStream can generally be solved.
