The battery fits of measuring very precisely in the Samsung NX300M. Klappert not and has no contact terminations. Thus everything chic.
The only thing that's too bad, is the battery performance of 750mAh. Thus, it is much weaker than the BP1130. But that's all in the description of the battery in it and who is buying the needs / at its should be aware.
CONCLUSION:
good, appropriate replacement battery. With unfortunately weaker performance than the original. But for the price fully OK
