I ordered this brush, because the SodaStream carafes simply after a certain time no longer be properly cleaned and accordingly ausschauen "gammlig". Since we have no dishwasher and the bottles you also can not so well cleaned with a normal bottle brush, my StreamBrush came in handy. The application is really more than simple, within a few seconds the bottles shine like new again and are ready for the next use. What I have to complain about, however, is still very steep price and the wooden handle on top of the brush. I think it's fundamentally uncomfortable with wet hands to touch wood (wooden cooking spoons, wooden meat tenderizer, rolling pin, etc.) and I would personally prefer a different material. Nevertheless, I would recommend it and the StreamBrush with good care it considers certainly forever, so that you can ever invest about 15.
