Battery grip is essential ...

... But I'm not completely satisfied. The handle itself is quite ok, the processing could have been better. Everything is not very stable. Have every time afraid that I abreiße the battery door if I replace the batteries.
The remote trigger does not work even after repeated battery replacement. Unfortunately, it is not possible to demand only to replace it. I still use a different, far higher quality trigger I've decided not to send the item back. Nevertheless, I think that's not okay.
The batteries work well, the quality and maturity I can not write much.
