- The battery: The battery is empty, the slower the speed of rotation of the toothbrush! With better models, the revolution remain until just before the battery runs out the same!
- Weak engine: As soon as I slip not only on the teeth, I burden the motor in the toothbrush-the revolutions fall again! Remember that not pressed firmly but easily!
- No 3D movements, alas!
My Conclusion:
Those who want to buy an electric toothbrush should also invest a bit of money. This toothbrush is more of an amateur among electric. The professionals are the Professional Cares on Oral-B! As you notice still significant differences!
