Good brush, but not long lasting ...

This is already my second Pro. Care within 2 years. The brush is at the beginning very well and even less the brush. The battery lasts in the first year, almost always 5-6 days at 2x daily use. After the first year, however, one notices repeatedly that the battery wears off and the brush simply has no power. Before the bought new, my old brush has (Purchase Date: 12.06.2012) only max. Two days held. That annoyed me a bit! Otherwise good value for naturally good!
