This device is my 10th. I had other more expensive American brands and all models of Braun. Frankly, what we demand in this unit is to remove small leftover food stuck between some teeth. I have many bridges and implants and have a vital need of this unit. No need to spend more. The rotating jets: it crashes all the time and it does not remove many jams. In addition it is much more expensive. This device is a value - very convenable.C'est the most powerful unit price at Braun. If you want better, go see and Waterpik among others, but it makes a very convenient service. Beware of handsets. I used every day of the electric brush (perfectly functioning) of a high-end handset at Braun, whose jet is dental Naze long time. It takes up space and discomfort in the bathroom. Prefer two separate devices.
