As I already had the predecessor Professional Care Braun. This electric toothbrush had prepared me for many years to come. The battery is still in full power. Wanted me now but even afford a newer model. Property me therefore again an electric toothbrush Braun bought. Looks like the "old" but as I said these innovations the timer is reminiscent of the cleaning intervals by a stuttering sound. Plaster head is somewhat larger here. The charging light is good. Overcharging is not possible. The toothbrush fits comfortably in your hand. Has a good leader. What more can I say. Again acquired a brown and I'm happy again. Other models I had not. So I can not draw any comparisons.
