Got delivered to my new Braun Oral-B toothbrush this brush. So far I have always set to the good old Precision Clean or Sensitive brush. At first I was a bit skeptical as to whether you want to be really as great as it extols you advertising. After some cleaning operations, I must say that for me are the best essays. You can tell the difference but felt like the bristles also well come in the interdental spaces. Of course, something always depends on the respective jaws and tooth position. An essay has kept me at a little over 3 months, and I am day brush my teeth twice. The cleaning power remains relatively the same until the end, because the CrossAction brushes from fraying so. So from me I can spend only a strong buy recommendation. But ultimately decides one's own feeling, which is always the top right.
