These oral irrigator does its job for the whole family. The stepless pressure regulation, the children come really great handle it. One should not think what's left makes the toothbrush between the teeth. If the hose after the warranty period "the Krätsche make", I'll try to fix it - either it works or it does not. But after two years he may go broke in my opinion, four people. But I also understand the other reviews, because if you eg only two or even only then you can really get angry. I can recommend this irrigator all because it is great !!
