I'm disappointed in the "new" brush TriZone. Four brushes move, three stabilize. Now that we have years with polished circular motion, mimicking the "new" the cleaning movements of a conventional toothbrush !!! You have to think about it! Of course, it makes more sense in the spaces and to clean off. This works the front of the incisors quite well, behind the teeth and at narrow but that's the posture angle very problematic! A round brush brushing always "right". And woe to those toothbrush switches off on time, if you take it out of your mouth: The shirt is ruined! Bathroom clean. The TriZone brush head makes its name and flings the toothpaste perk 2m wide. Incidentally says "Stiftung Warentest" 04/2013 on p.22 to "three-zone has the technically complicated bristle Overall she cleans thus no better than satisfactory." The winner (1.5) "Braun Oral-B Vitality Precision Clean" costs just one 22.00 EUR. Which by the way has a round head brush. Overall, a weak performance by BRAUN. If you want to use it yet, should change his brushing technique, as shown in the video!
