Nikon MB-D10, 2 Junk Units

Set of 2.
These are likely one genuine and one non-genuine, but please check the photos.

One was dropped and will not power on even when attached to the camera, and the holder lock is also not secure.
The other has poor contact and has not been used for about a year.

Both are junk.
They likely cannot be powered on or used, so please consider them only if you can repair them or need parts.
