Battery Grip Kit for Nikon D850 Digital SLR Camera - Includes Qty 4 BM Premium EN-EL15 Batteries + Rapid AC/DC Battery Charger + MB-D18 Replacement Battery Grip

Worked and fit wellaa A++++

Battery capacity is good. Using it for my D850. Quality for the price is great.

Excellent just as good as Nikon products but not as expensive.

I see no improvement of frame rate but decided to not return it because of the batteries. Time will tell if they are comparable with Nikon batteries. There is a reason it is a third of the price of a Nikon grip.

Super fast shipping and just as ordered all perfect. Thank you!

Would not call these batteries premium. The four batteries that came with the product do not work in the Nikon D850 battery grip. They worked inside the camera body, but the battery icon in the camera's display kept glitching. Do not trust the battery life after seeing the glitches. When I placed my genuine Nikon EN-EL15b battery into the grip, it worked. Something is wrong with all 4 batteries they sent with the product. The grip itself, is ok, it's plastic and you will need to be careful attaching it to the camera body. Their picture of the D850 grip is not accurate to what the actual D850 grip you will receive. Which is good, otherwise it wouldn't fit. Should have spent the money and bought from Nikon.

Ordered the battery grip via Amazon from Big Mike's Electronics and had it in my hands in one day. Fast, efficient service and the product was just what I needed for my camera. I would easily do future business with Big Mike's Electronics. A+!

Only disappointment is that it only holds 1 battery at a time!
