After my old Oral B Professional is broken, I have long wondered whether the 8500 DLX is their money worth. After I found out that the Oral B was 8500 winner at Stiftung Warentest 11/06, I bought it. She really is the best toothbrush that I've ever had and nothing compared to the "normal" Oral B Professional that I had before. The teeth are really clean and smooth within the brushing time of 2 minutes. Thanks to the polishing article removes the toothbrush even coffee and tea deposits on the teeth that I get away until now only with special toothpaste. The only (really small) "drawback" is that they are a little heavier in weight than the other Oral B toothbrushes, I had so far. The Braun Professional Care is in my opinion a truly recommendable toothbrush and the best I've ever had !!
