Before toothbrushes user "manual" I went on 5000. Brushing is incomparable and a lot more effective. My dentist and my orthodontist me have noticed.
There are 5 modes available, I use only the first, strong and traditional brushing.
The other four did not have too much intétêts in my eyes, and are mainly used to justify a higher price.
The green light turns red when the pressure on the teeth is too high or that it is used poorly.
Every 30 seconds, a small beep sounds indicating changing area.
The small electric clock is really convenient, it indicates the brushing time and to duration of use makes a happy or sad smiley. It comes with what the fix on tiles or mirror.
You can buy different types of brushes to adapt (classics, for dentures, whitening ...). I am glad Oral B classics, avoid generic that really take bad.
The handle has a positive point that I particularly like: there is no small inaccessible areas in which could accommodate toothpaste. It can therefore be cleaned easily.
In terms of battery, there by cons few flaws: the charging time is too long, several hours for only a half hour max brushing. This can be annoying when traveling. A larger capacity battery would have been nice.
The small clock batteries also discharge too quickly but it is not necessary to use the toothbrush is not annoying.
In conclusion, a very good buy I do not regret at all. Try it and adopt it!
