Cheap, works, has quirks!,
This review is from: Neewer Pro Battery Grip for Nikon D5100 5200 D5300 DSLR Camera Compatible with EN-EL14 Batteries (Electronics)
First, I don't think Nikon planned to make a battery grip for the D5100 or D3100, because they did not include contacts inside the camera to accept signals from the shutter button on an grip. Because there is a demand for the function, the copycats went to work and made this gadget and many similar versions of it. They are not made by Nikon, of course.
It's cheap. A Nikon version would cost 10 times as much. It's not Nikon quality and it feels a little flimsy. It works, but... Sometimes the camera says the battery is not compatible with the camera, even if you use Nikon batteries. It seems that re-inserting the grip in the battery will somehow get around this. I don't understand why, but this works. By the way, there are other versions of this available elsewhere that come with the an extra tray to accept 8 AA batteries, but for some reason they are quite expensive ($100+).
It comes with a short external cable that goes from the grip to the camera remote shutter connector outside the camera -- not elegant but functional. It allows the shutter function on the grip to work (that's what Nikon left out inside the camera). Possibly Nikon thought nobody would ever want to use a grip with the tiny D3100/D5100 cameras, but of course people do. One of the main reasons is that this grip also allows you to use very cheap $7 clone batteries instead of the Nikon $41 batteries, which for some reason you can't do with the bare camera.
I have not seen it from Nikon yet and the D5100/D3100 cameras have been out for a long while now. I don't think Nikon will ever release a similar product, because we're close to end of life on the cameras. By the way I have seen products with Nikon Logo packaged in Nikon logo boxes that are called Nikon MB-D31 or MB-D51, but they are brazen fakes. You buy them direct from China or Hong Kong on another website. They are not listed on the Nikon USA site. Nikon does not make them -- they are complete and utter fakes from the land of poison milk and honey.
So there is more than you ever wanted to know. If you buy this, you should be braced for its quirks. I gave it four stars because for the price, it works well enough.
