The toothbrush like me getting better. When I tried the toothbrush for the first time I was only a little skeptical. But now I can say, but the good brushing the toothbrush with the brush head rectangular teeth. The mouth should be kept slightly closed while brushing, otherwise give small Spritzer.Sie fits comfortably in Hand.Ich think with the Oral-B TriZone the teeth and gums are perfectly cleaned and maintained. The price performance ratio is okay. Anyone looking for a toothbrush with some extras is very good advice with the Oral-B TriZone.
