Great brush differs from the Russian 100%. After this purchase realized now I will buy only here, beautiful, clean, comfortable, does not injure the gums, will definitely buy more, made in Germany, super quality, just happy me and my family! Already booked again for the year ahead, in stock, cleanses for their value, 5 points, 100 times better than the Russian, dentist confirmed, he does not fight. It cleans great!
