On the quality of the batteries also nothing to complain about - they fit perfectly into my phone and also the performance is top!
But why I give only 2 stars is that the charger does not consist of one part, but from a shaky plug design. The short time only is suitable for charging the battery requires.
Since mitlerweile my phone can be loaded garnichtmehr via plug - I am dependent on this type of battery.
And if one evening inserts the replacement battery and am still not full, because the device had a bad contact due to poor connector again - you're very frustrated !!!
The batteries are great - but the charger is very bad !!!
