Have this brush acquired to ridiculous 46, a real bargain. Nothing on the brush is too much, nothing too little. (Yet) good acculeistung keeps for one week when I brush every day 1x. Foamed very well on the toothpaste, brushing excellent gumline and tooth necks, good interdental cleaning. Can pass as gently, although it also feels like that cleaning is very thorough. A bit It feels as if a an air cushion, no, a brush pillow away shimmers over the teeth. Finally, it is Oral-B managed to get hold of the cleaning performance of the Philips Sonicare, without sonic technology, but at least. The Oral-B sonic toothbrushes were lack constructed from start to finish, completely unusable. Toll is also the very favorable price. Another advantage: should not like any of the Tri-Zone-head, you can still use the usual Roundheads. Very variable.
