Developed to brown

I use Braun Oral-B electric toothbrushes for about 20 years. Over time the more and more features of the battery were the cleaning frequency higher and worse.
This was consistently maintained. But that's enough nciht Brown goes even further by and missed the battery now has a charging time of 24+ hours!
The toothbrush is often used more than 2 * 2 minutes a day of me and my wife together. I would estimate we come together on approximately 12-15 minutes cleaning operation per day. The toothbrush must be every 3-4 days to the current latest.
If the battery still is aging, this model will probably hang within a year at the current permanent.

Clearly too expensive for me the last wars Oral-B, the next time the competition will get his chance.
Device does not go back just because I need a toothbrush ...
