After my previous Braun Rotationskopfzahnbuerste slowly gives up the ghost after many years of faithful service, I decided after intensive research on the internet for the Sanitas SZA 90 Schallzahnbuerste. The delivery was fast and full of joy, it went to the first brushing teeth. The feeling was incredible. The brush produces a sound that is reminiscent of a flying bee. The - compared to my brown - very soft brushes so tickled at my gums and palate, it has literally driven out my tears. After about three or four days I then got used to the feel and have from then Schallzahnbuerste very often used. Brushing hinterlies a very thorough feel and actually I was very happy with this machine from that date. Unfortunately, I could not enjoy the very long, because the machine was broken suddenly by about two and a half weeks, ie the motor went - not despite vorschriftsmaessiger initial charge and discharge. The return and refund my costs has exemplary folded, so I'll buy more for a star, so instead of a star now two.
