I speak mainly on the speed which I found impressive during the first use (especially since I wear a composite one of my front teeth that I was afraid of losing it so much m 'appeared aggressive) and the sound that is reminiscent of strawberries used by dentists.
We made it progressively, but it does not harm the enamel of the teeth in the long run?
From what little I could use it for the moment, the value seems to me more correct (thank you to the brand ORAL B have provided for all budgets).
Most:
-the Price,
-The Timer that changed my life
-The Pressure sensor,
-The Battery life,
-The Feeling clean (the cleaning is more effective and feel it)
Cons:
-Agressif?
-length wire for the charger that is much too short,
-The Body of the brush is completely sealed it with toothpaste dripping on to every time I am afraid of damaging it?
-Only One brush is proposed not recharge.
In conclusion, very good buy but to see the long term.
