I must admit I do not like the design of the toothbrush. The oval, sloping upper part it seems somehow like retro-futurism which is based on the 50R-years. In addition, the whole really is a sham because the motif princesses only appears on the brush approach itself. "Girls" - and "boy" model differ only in shades of colors. But, for the sake of fairness: you can already see that there is a child-friendly equipment; The child in any case, I've given it was completely thrilled, though it was allowed to use a previously discarded adult brush. Of course, this model is not the high value as in the "Professional" series is given. Everything looks a bit rickety, less costly. For example, there is a signal-jerking only at the end of two minutes cleaning-time, and not in between, in order to structure the individual concealed sections ... But the brush will be surely used with adult supervision and a "purchase for life "you need not to be expected with this device and design. This is also on the manufacturer side, the low price is not her. Overall, the ratio of price and performance ratio so.
