We bought the two toothbrushes Almost exactly two years ago. First the positive aspects. The battery lasts at the beginning (about the first six months) by about 5 days before it must be recharged. The cleaning results fall very well by the high Pulsationsraten. The product fits well in the hand and the red warning lamp effectively helps in controlling the print run. The various cleaning programs are a nice gimmick in the end, we never use them but actually. In itself a good product. Unfortunately, the manufacturer has created but the battery is a true money-making machine. The battery is permanently installed and can not be changed by me as a layman. Would he keep for years would be to get over. Strange is as whole but if continually degrades after the warranty for both devices the Battery and barely survives more than a day without recharging.
Not recommended Very good cleaning results due to the disposable designs: Conclusion.
