We previously had a sonic toothbrush Beurer (Janosch), which was very badly worn within less than two years (leaky floor, brittle casing, decreasing vibration performance). In addition, the brush of poor quality and always consumes very quickly were. The shaft droned as quickly. Probably a reason why there is no longer the beurer. When Sonicare the high quality of the materials was apparent to me right at the beginning. High-quality plastic housing with thick rubber coating, metal insert at the toothbrushes (prevents sagging of the brush stem and ensures better vibration transmission), refined and especially small (touring suitable) charger, good tactile feedback of the waterproof control buttons, etc. The engine power fascinated as well. The vibrations are transmitted with a lot of power and absolutely stable on the brush head. The noise level is surprisingly low. Even the sound conveys solid technology, almost as if this sound designers were at work. The discharge of the battery during the cleaning process can be felt in any way. The vibrations remain absolutely constant and can not (similar to those used by Panasonic linear motors) after. Absolute sense, the choice of two vibration strengths. Associated with this also changes the timer signaling: In case of slight vibration setting the plaster 4 quadrant advisory tones through a shorter interval than by excessive vibration setting. Good for kids who are just starting with the brushing or have never electrically cleaned. The toothbrush can also here with - the intervals are extended automatically for multiple use. However, this function can be deactivated also if you want to always have the same intervals. The vibration intensity can be had only with the motor switch. With the engine running, the selection button is disabled and can therefore not be pressed accidentally. A nice idea are the replaceable front designs. In the embodiment, however, is not about plastic cover, but merely labels. So if you should opt for a different design, so you have to unfortunately dispose of the old film. Nevertheless, keep the films very well. Since already six months glued to our brush the same film without peeling somewhere. The conclusion of our children much more pleasant than the old. Brushing makes them with the Sonicare definitely fun.
