It is now several years that I use a toothbrush Oral-B, and I do not think it was possible to do better. Yet this is the case with this latest model, and improvements are sensitive. First, the heads of the rotation speed has been improved, which influences very favorably on the quality of brushing. The toothbrush brand mini stop operating every 30 seconds, to help us evaluate the time spent brush each area of the jaw (front, back, top, bottom). By following this method, you get a perfect brushing and smoothly. The brushing is done by measuring the pressure of the brush on the teeth and gums. If the pressure is too strong, a little red light comes on to let us know. There are 4 models available electric brushes. Although not having tested the Trizone 4000 (which is supposed to improve the whiteness of the teeth), it Trizone 2000 model seems perfectly effective. I do have a bad word to say about the length of the feeder wire: a little less than a meter. My outlet is high above the 'work plan' to the bathroom, and the charger when plugged hangs into space ... It forces me to use a different socket to recharge my brush. It's not a big problem, because the load takes about a week, but I think that Braun should review this detail. For those who have never used this kind of brush, I'm sure he will discover an object indispensable. Those who have an older model will experience a pleasant surprise!
