Neutral:
* You have to make the same movements as when manually cleaning
* For people with sensitive gums possibly unusable (bleeding)
Negatives:
* Design errors storage of brush heads. As noted in other reviews, Mold may form due to storage inside the head. Although this does not come to the actual bristles and is also relatively easy to remove, it is unpleasant but definitely. Drying by Qtip or alternative storage help here
* No battery indicator
* Battery inertia effect of NiMh after less than 6 months palpable. Initially the battery for two people held more than a week. Now can the cleaning performance after only a few days to clear. A short break without charging station would now no longer possible
Conclusion:
Actually a very nice and well cleaned toothbrush. Unfortunately, with a very unterdurschnittlichen battery (see other reviews). I play with the idea to return for this reason the toothbrush at Amazon (has yet to find an alternative).
