The toothbrush makes a qualitatively very good impression, she cleans well the teeth. If after a few days of use begins to rust, the slip-on device of the brush that is simply not acceptable. It looks like stainless steel, but it is not. We used ordinary toothpaste of Dentagard and even the slip-on device after use water cleaned as it says in the description. Am disappointed by the poor quality of Oral-B.
