Both quietschbunten bottles are always worthwhile. They fit perfectly into our SodaStream and it also runs next to nothing at the bubble! Although we previously coped well with the large bottle, I was angry to have not yet bought your little earlier! They are really ideal for the office, for children or just on the go. The pint bottles fit well in any pocket and are even easier to clean in my opinion. In addition, you do not like the evening a whole liter of soda, where the next day probably only the plants benefit from it ... What I wanted to say, I find it extremely convenient for small thirst just come to have even a pint of water gushing. I hope the bottle's soon in other colors in the set. highly recommended!
