Question: I cant get the grip to work at all. The camera recognizes that its attached and i can select the grip ,but nothing functions,how to fix it
Document: As the title says, it basically provides all you get from the official grip at a much cheaper price. The wheels seems a bit rougher but other than that I don't think you'll be disappointed with the build quality.I took this on an informal shoot that spanned around 3 days. It held up exceptionally well attached to my BlackRapid at my side. I was a bit cautious at first that it might break, sending my camera tumbling down but my fears were unwarranted.
Once I attached the grip, the "feel" becomes less noticeable and really becomes by my account, an afterthought. All of the buttons functions just fine and do what they are intended to do. The "grippy" parts feel really solid and you would be hard pressed to discern too much of a difference (if any) from the grippy parts of the original MBD12. Also, the two dials don't share the same feel as the original, but they function just fine.
I have two Nikon D300S's and I Couldn't Do Without the battery grip for either one. It makes holding the camera so much easier especially when you put a heavy lens on the camera. And it really gives you the added battery power that you need. Stay away from getting a "double" battery charger for the batteries on this as it doesn't work and you can't get your money back. The generic battery works just as well as the nikon battery. I would recommend either. I use both.
With the grip attached, I can have my D800e frame rate bumped. The slot for saving the rubber seal from nikon D800 body is a good design. I don't care much about the control buttons and wheel. As long as I get the desired frame rate and I am happy. So far so good. No complain here.
OMG, this Meike Grip for my new Nikon D800 is AMAZING, repeat "AMAZING!" The quality and build is very good and on par with the Nikon MBD12. All functions are the same and worked out the same as the Nikon MBD12 in my full-on tests, so will not get into that. It arrived in great shape and when I installed the ENEL15 Nikon battery, it was a bit tight at first but with the second time I installed the battery, all went smooth as glass.
All the electrical contacts work and all the menu functions also work. A great buy
Within an inch or two someone probably has to tell you its different if you didn't know it was non-nikon product up front. The vertical release button has a nice autofocus detent and then shutter release that is easy to use and while the feel is different than the nikon button it doesn't feel cheap. 100% of functions work AFAIK after just 2 days of shooting with it and 8 AA's are working great with it for me.
The Meike's wheels work fine but are just slightly less tacky to the feel. I notice my MB-D10 grip on the D300 has rubber coated selector wheels. I assume the Nikon MB-D12 grip has them as well. Okay, so you don't get rubber coated wheels when you save $400. Be aware that if you really use the wheels a lot, the one under your index finger when shooting vertically feels more recessed and is definitely less grippable than the rubber coated models.4.
well, what do you expect for $50?....it was good for about 15 shoots... now it wont stay attached all the way. You get what you pay for. Dont get me wrong its great for its price cuz you can buy 8 of these for the price of 1x nikon.
I looked at my MB-D10 on the D300 and its pin is plastic too, so it should be okay. The camera recognized that the grip was attached and reported battery status.As with the Nikon grip, there is a recessed place to store the camera's rubber cover that you remove from the camera's base to expose the grip contact interface pins. Nice.
Answer: First...assuming you are using the 8-AA battery box...once the grip is attached, remove the battery slide and than reattach. You will know it is working if you look on the display on the camera. Directly right of the icon that shows the remaining battery life it will have the letters BP which indicates the power is coming from the battery grip. Also in the camera setup menu go to the option that lets you choose if you want the power to first come from the camera or battery grip...select the battery grip. If you are talking about not able to use the release button on the grip...make sure you rotate the switch next to it so the indicator points to the white dot which selects the grip controls. Finally...do you have the stock battery in the camera plus the one in the grip? If all else still doesn't work....remove the grip and reattach...perhaps the contacts are dirty or defective. It should work...mine works perfectly and is a cheap  replacement for the Nikon unit that is identical in performance and looks. Last thing...if all else fails you may have a bad one so return it.
