Brush prima, battery scrap ...

The outstanding qualities of OralB 5500 have already been shown extensively and numerous.
But there is a major shortcoming in the apparatus, which tend more toward battery. See also many items on the web and at Oral-B on their website or forum ... actually the problem is already known forever, but will not do anything, because to replace the battery is not in my opinion purposeful, more of a gamble, if he will last longer or to "special" advertised!

Problem:
Brush end August 2014 bought. In operation from mid-September 2014.
Since the beginning of December the following behavior: Brush fully charged (! 2 days) - that is, no longer flashing, all bars present in its entirety. Take brush in operation and enjoy after enigen seconds to a maximum of 1 minute after turn-over that no beep and does the battery is dead simple. The behavior is now repeated across days.

Brush now posted and hope to find a new one that I will return and I will buy myself another, higher-quality model. A repair can mE to tide over only temporarily this defect.

Undeniably the cleaning quality of higher Oral-B products is perfectly - for years has my dentist is no reason to "Clean up" or the like, therefore, to buy a product again the effort!

Source, as already mentioned: the Web and Oral-B itself!
