Even exchange failed, but very courteous Installation Service

Today it has become customary to throw a device when the battery is weakening. The environmentally conscious is electronic waste but an eyesore. Therefore, he tried to replace the battery pack. On Amazon, I came across "Akkutauschen.de" to an appropriate battery. This a "Battery replacement made easy" should be accompanied -Anleitung. Was also only required the exchange considerable skill and experience in dealing with Zänglein, soldering iron and solder. After some pottering supposedly finally made the device remained inoperative. So I wrote a mail to "Akkutauschen.de" and I promptly received a polite and responsive answer, I may send the toothbrush with charger to test and repair to the company in Hamburg. This I did, and soon I got everything working perfectly sent back with test certificate. The 10, - for this effort pay gladly. My advice to the layman, to have the battery replacement make by the company. Unfortunately, I had not known of this possibility.
