Still not optimal

When switching from on-Vormodell 3D Excel should be noted that the new Triumph much better dressing, is quieter and more pleasant. The brush itself is significantly more cumbersome (because wide), especially for children. The brush heads can not be cleaned easily and still give their grooves, angles and cavities one always felt that this thing is not really clean. Quick change times are not splashing around in the high prices. The display can not be seen, which would have been inclined at an upward orientation feasible while brushing. Decisive disadvantage: Despite the high price still a NiMh battery and no lithium battery (you can see the brush is not always possible in the charging cradle without sacrificing long term performance). Thus the "death" of the brush (like my 3D) preprogrammed by two to three years! Only 4 stars because of the good cleaning performance.
