The worse batteries to get

I hate leaving bad reviews but this one is deserved! I decided to give these a try and order a dozen of these for my d750. I shoot professionally and these have stopped working mid shoot and mid weddings with no warning. Over 75% of the batteries have failed and the others have issues communicating with my Nikon bodies. They keep on sending me new ones but it just keeps failing over and over. Vivitar has some serious quality control issues and I cannot recommend these batteries. OEM are by far the most reliable and if you rely on critical work just spend the extra on it. The wasabi ones are also a hit or miss but are by far more reliable than the Vivitar ones. I Don't recommend these and look elsewhere for batteries.
