Durable YES but you can not keep hygienic saber that would only if they would zulegbar why even a star

On the performance of the oral irrigator I can complain about any defects, but with the hygiene, it is a disaster, was shocked when I from the water tank valve more closely took down the space in the small spring was full of black mold but it was still worse not only in the mouthpiece and only below where the water is removed from the cup, it was the worst first I tried a piece of rolled-up paper towel then with a toothbrush that would not end. Have now decided to stop using the oral irrigator. These problems I had with my previous "Princess" - never had - not von Braun. See Image
