This rechargeable electric toothbrush comes with a multilingual operating instructions and that was very helpful to my departure. Once i had correctly identified the different oscillating-rotating brushes (three are provided: smooth polishing / brushing accurate whiteness / plaque, but others exist) and that i understood how to pass dun scrub mode to another (smooth polishing cleanliness / white gum care), I found the unit comfortable to use, especially with the end of each brushing a real feeling of cleanliness. Japprécie much pressure sensor (a red light lights up if too much pressure). The thing more: the SmartGuide (small wall clock with batteries included), connected wirelessly to the toothbrush, poster mode and brushing time. You can disable the radio transmission (eg for the aircraft, hospital, or as a precaution against a pacemaker) by simply pressing three seconds on the power button of the same operation brush off to reactivate. During brushing, a slight change of pace every 30 seconds indicates that it is time to change zone (also seen very well on the small pendulum) .A hard plastic case is provided to transport brush and two brushes. A quality product, to see on the long term.
