Very good idea - implementation partly deficient :-(

So far, I was with my original Nikon Battery grips (MB-D100, MB-D10, MB-D11) very satisfied or maybe spoiled !?
I would also re-elected a original battery grip, he would have been available only to a "reasonable" price.

Decisive for the choice of MEIKE MK-DR750 was not least the integration of the 2.4GHz wireless remote control.
In addition, you read about the Nikon MB-D16 currently not much positive ...

I use the Meike Battery Grip for about 5 weeks.
My BG can be free from tensions mount the body and also sits firmly.
Problems with contact I can not determine.
In the Camera menu, the handle is displayed as MB-D16. The dials, the release button and the navigation button is respect for me. Feel and function satisfactorily and quite comparable with the MB-D11. At first glance, therefore, a successful product.

The timer functions and the supplied battery compartment for AA batteries, I have not tried it yet.

The stability / rigidity of the plastic case is compared to me known Nikon handles significantly worse.
When using the stand with slightly heavier (zoom) lenses are the handle "spring" after.
He has very little stiffness and can deform the extent that visible gaps between the handle and body arise.

The remote trigger was at close range (He can, however, only use as long as the battery grip a charged battery is inserted.
The battery in the camera body does not power the radio receiver with power.

The energy issue is the biggest shortcoming in my grasp. The batteries are sucked literally empty during storage.
If the handle stored separately from the camera, then the paper loaded in the BG battery will lose "only" by about 5% per week.
At first I thought, the power consumption is related to the receiver of the radio remote control, which obviously can not be switched off.
When mounted, the battery in the battery grip BG discharges when the camera is about 20% -30% per week - so even faster.
Obviously, the BG communicates with the switched off camera - visible even on irregular flashing green LED on the back of the camera ("Access Indicator Light of the Memory Card").
Even worse is when you remove the battery from the battery grip and the BG can be bolted to the body.
Under these circumstances, the battery in the camera body discharges by an incredible 70% - 80% per day !!!
In comparison, it should be noted that a discharge in the camera body without battery grip also after 4 weeks is not yet discernible in my batteries (
As a way out, I only see the BG remove the storage of the camera and remove the battery from it.
Too bad - in these circumstances is the BG not really often used.
