Oral B is THE reference for electric toothbrushes. The mark "Made in Germany" offers here an improved model of its Pro version 4000. For additional twenty euros so we are treated to a small digital clock to stick (batteries and fixing system are provided: the hardest part is put the machine on time because you have to play with two very discrete white buttons BEFORE CLOSING THE CASE). This magical clock shows, dice the initiation of the brush to clean the oral area and after thirty seconds to process invites the next sector, wincing when pressure is excessive. After two minutes, a big smile indicates that the brushing is complete. As the brush itself transmits the same information through other codes (vibration, LED lighting) we do not have to park in front of the clock during brushing ... phew! The travel case is anything but a gimmick: it avoids brush (including the charge time is longer than twelve hours) to get in close walking in the baggage. For long absences, the recharging base, the same as previous models, is a very small volume. The real novelty of the Pro 5000 is a very gentle gum massage mode for which the special brush is provided with two other models, which can guide the choice of replacement accessories. More interesting than the digital clock, "gums" mode is the real novelty of a brand that, for a high price indeed, continues to innovate.
