I usually order my brushes Oral-B Braun; but this time I'm totally disappointed with the product sold. I think being a victim of counterfeit products .... After a few days of use; there are more than rotation of the brush (just a residual vibration) and the letter "Oral-B" is erased! Moreover; a huge game is found at the brush head. FYI, the packaging text is written in German. I will request the return of these products at Amazon and refund or exchange against certified products Oral-B Braun.
Additional Details: The seller is kath.lee2007; He immediately contacted by apologizing and making a refund without returning the offending products.
