My Spudler was now anyway a few years old and the closure hooked sometimes.
Hoping that SodaStream has corrected the design flaw with the latest model, have simply ordered him time.
And lo and behold:
Wonderful !!! No more flooding, the shutter works (so far) and it perfectly fits better visually in my kitchen!
The plan is therefore risen and for those who have the same problem with the floods and now speculate whether it works well with this model, I am writing this review :)
Generally I find the possibility that water in a glass bottle to spudeln super and simply because of bacteria and plastic bottles taste me no PET solution comes into the house.
This has already earned 5 points for me.
