Unfortunately, almost good ...

The case makes a good impression and mechanically sits firmly attached to the camera. The controls thus switch and wheel is for me okay. The tripod socket on the bottom is reasonable anchored, so my opinion is given no danger to tearing out of the socket. The slots for the battery / battery have some play; so that I can live with that. The rubber coating ("leathering") has been at one point something bad cut before you pasted it. But that is hardly noticeable on.

The handle is properly recognized by the camera. I leave the battery in the camera and insert an empty battery holder in the battery grip; which is interpreted correctly by the camera => Full battery in the camera / spent batteries in the Battery Grip.

Next, I leave the battery in the camera and insert an empty battery holder in the battery grip: The camera turns off completely with the message "battery low"! I have repeated many times with different input parameters.

I do not know now, of course, whether the battery grip or battery holder is damaged. Maybe it is also a systmatischer errors and occurs in all articles. The item will be sent back to me without any exchange, I expect little prospect of improvement.
