The battery doesn't last long as the regular camera battery, it let me down on a middle of a wedding reception. I am glad that I had a secondary camera by that time.

Great addition to the Nikon D750. It helps when taking photos vertical so you can have a normal grip on the camera instead of your arm laying on top of the camera. It also can give you extended battery life before you have to charge the regular camera battery.

Easy to hang on to the camera

Just received the MD-B16 for my D750 and contrary to lots of reports, this Nikon battery grip is sooo much better than the third party grips (in my opinion.)
Had a third party one on my D90 and it was functional but the Nikon one here is clearly the better product.

Durable; Easy To Use; Improves Product Function; Lightweight

works well

Problem: Can't get one right now . the Nikon MB D-16 is a hard to find item and on backorder everywhere. Warning: The after market brands are reporting battery drainage problems. You just have to put your name on the waiting list, like I did and wait for the real nikon MB D-16 to come in.
