I opted for the Braun Oral-B Professional Care 1000 because it has a very good cleaning performance with 8,800 rotations and 40,000 pulsations per minute. The higher the numbers of revolution plaque and other deposits are removed the better. The toothbrush fits comfortably in your hand and is easy to use. Figure 2 minute timer shows every 30 sec. By a short stutter and after 2 minutes by briefly faulted the cleaning time. I think that is a great help to the correct brushing time recommended by the dentist observed. I just wonder why two minutes brushing time will be displayed, where but the recommendation by the dentist is brushing 3 minutes. What is positive, evaluate the 30sec the. Continue intervals after the 2 minutes and thereby no Proplem is to gauge a longer time. As a shortcoming I find the Pressure sensor that does not deserve the name. According to the manufacturer the toothbrush showing through a red light and stop the pulsating movements to too much pressure. However, I have pressed so hard brush, which I'm afraid to break them and to hurt me before control reacts gums. The Pressure sensor is probably something for real Grobmotoriker and for those not recommended.
Conclusion: The Oral-B Professional Care 1000 has a great value for money and I would buy again. The teeth feel after brushing to clean and smooth.
