Here is my experience about the product:
The workmanship is very good, the materials seem rather high. The packaging is made of paper and kept discreet. The battery is mini-fit for the S3. Not as small or as large! When the batteries are Drittanbittern often a little too big, so you have to push it a bit tight inside. Here but remove the battery pack is not so simple. One needs to support a pointed object such as a small knife or a small pair of scissors. But check it super easy. The battery can be removed with the fingers without effort.
The capacity of the battery is 1500mAh. When you load any abnormality was found. The charging time was about the same length as the original. The term is also good. For originals I could feststllen no deviation. As with all smart phones, the battery life is comparatively very low to the old classic mobile phones and, of course, depends very much on the personal use from. When S3 mini I have earlier noted that, for example, the UMTS connection the battery very stressed. Therefore, I have tried to achieve similar use for the test.
What one can say is that the battery pack with any store unfolds more and within 3 - 4 Load reaches its full capacity. Therefore, do not expect the same when it first loads, that the capacity is at the maximum. And always be running out of power until the smartphone is plugged in again.
Conclusion: I would highly recommend the battery. He is fit and Akkuleitzeit is also at least as good as the originals.
