I ordered this brush, because my previous Sonicare model "HX6930" was once broke down again (for details see. Write to HX6930). Instead of outrageously expensive replacement handpiece the 6930 series I decided this time for the model 6510/22 because wesentlcih conveniently available and, moreover, a current Sonicare model. My Impression: -------------- . + Sleek and lightweight body; + Very easy processed entry level, but it is relatively inexpensive; * Housing made completely of Hartplasik, rubberised grip recesses, * Only Power On Timer, no different modes can be selected; -not exact battery level indicator with multiple LEDs; -lt. Technical data geichen the pulse movements like the old 6930, but this I can not fully confirm. I had the impression that the old HX6930 was stronger! -> It will be interesting to see whether these new simple models of the 6510 series, the long-term quality has improved ... (Will possibly report)
Price / performance ratio, however, is (at External link) ok .; outside commercially against unreasonably high.
