Vorneweg I want to say that I was very pleased so far / am with my electric toothbrush: Braun Oral B Vitality Sensitive Clean current price at Amazon: about 20 Euro. Secondly, I have more sensitive teeth or gums. Ie I naturally compare inevitably this new product with my "old". And since the new product, the "electric toothbrush Oral B premium TriZone" gets in trouble. It is difficult, it is loud and it costs a lot more. Sure, there's still the "SmartGuide", the timekeeper with Pressure sensor. But somehow that's frills and not really apt for me. The timekeeper spread hectic that I just can not make use of the morning and the Pressure sensor is out of order, if you have the machine set to "sensitive". What I have also done because of my sensitive teeth. So I am sorry to say: This product brings me personally. Therefore, the device will now be re-packed neatly and there by my side, unfortunately, only very subjective 3 points.
