Very satisfied 524

I now have this toothbrush for several months to replace a low-end model of the same brand whose battery was getting tired.
Brushing is very effective, the power is with go. And all without bleeding gums. There has improved compared to my old model.
The build quality is excellent.
The battery life is very good: a dozen brushings. The loading is against a little long.
There is a system of "beeps" that lets you know how much time to spend on the side, top, inside. With each beep, the brush stops for a short time. Personally I could do without this functionality, it does not seem very useful.
