The Meike and Zeikos are not available on Amazon or BH Photo. There are a few genuine used Nikon MB-D11's on eBay, so I will start to fish in those waters.
Some chatter on camera forums months back touched on a weakness with 3rd party battery grips for Nikons. Apparently, the charge condition of the EN batter in the group was not being indicated on the Nikon camera menu. In the Set-Up Menu, I believe.
The circuitry in the group wasn't correct. And supposedly, only the genuine Nikon EN battery has a logic chip to accurately communicate with the camera. But you know what they say about a 'little knowledge' being dangerous knowledge. This might be bogus information.
I've already got a bid on eBay for a MB-D11. And I like the idea of transferring the camera EN battery to the grip to save weight. I really don't see a need for massive shooting capacity.
