Prefer the Nikon product
Having tried third party grips for my D7000 and finding it didn't work, I went to the Nikon grip and had no issues. Decided to go to Nikon again for the D7200. Yes there are dearer than third party grips but have not had any issues with either Nikon grips.
Easy to use, Build quality, Battery life
