Review (5/5): Everyone should have an electric toothbrush!
This toothbrush has saved my gums and prevented many cavities.
Since I use this toothbrush I have much less inflammation of the gums and I only got 1 cavity (while I used to have more frequently). It does a great job and holds the charge well (I went on a 3-week trip on 1 charge).
I would recommend replacing the default toothbrush head provided (small circle) to the dual clean head. Why limit yourself to a small work surface when the toothbrush could brush double?
