The battery power of my Braun Sonic Toothbrush has now had only 30% and take a new brush for about 200 to buy I tried the battery replacement service for not even 27, for all other functions of the device were still properly. It's just an annoyance at Braun toothbrushes that a consumable item such as a battery is not easily replaceable. I ordered on Wednesday evening, Thursday the shipping container because, Friday was sent off the device and on Wednesday it was all back again. When a return delivery service report by running exchange work and inspections is. The charger being broadcast was also checked for free and measured the charge power. The amount ended up packaging is very suitable for the purpose and shipping instructions are easy to understand. The package is again used for the return mailing. Conclusion: all-round sustainable, good value for money and highly recommended.
