great, but very weak battery performance

This toothbrush is itself wirkklich great and worth the money. However, only as long as the warranty runs. After nearly 2 years, the performance of the battery is so weak that the toothbrush "full battery" during the 2-minute brushing simply emanates spite display. This is not akzetabel for a product in this price range. The worst part is that they "fully" indicates during brushing and then is empty, so you can not adjust to the fact that it is actually empty and they could charge before each (!) Cleaning.

Conclusion: For those who want to buy a new toothbrush for> 100 euros every 2 years, this is an absolute buy recommendation, who wants more sustainable products should urgently leave it alone .....
