Rarely have I seen such a senseless and überteurtes product. Here Sodastream is probably on Stupid Catch!
The cleaning of the bottles (since they are not dishwasher safe and the expensive one - can greet lust commercial - bottles for kaufem must) is difficult and expensive. However, there are a hundred times more favorable variants as these Tabs!
As would be the one dishwasher tablets. Here is enough for half a day, leave overnight, finished.
I use Sprudeltabs for cleaning the Third. Since 136 costs something around 6 euros. And here cost 10 pieces less than 5 euros, per Table 50 Cent! That's a rip, nothing more.
