We have probably caught Monday pieces, after only 5 weeks and the second charging are 2 of 4 batteries measured with our digital multimeter dead. For this we draw from 2 star. The Amazon Customer Service has exemplary and react as desired: Although the 30-day returns window has expired a week ago, there are now after a brief telephone conversation with an exchange replacement. Hopefully the new batteries correspond more to our expectations, because in principle it is a space-saving and well-functioning charger with suitable batteries at an affordable price.
