I purchased a third party battery grip from eBay (Neewer) to use with my D7100.
While the grip has worked 100% as advertised, I was never in love with the fit and finish.
It also flexed (pulled away almost 1/4") when mounted on the camera, to the point that I was concerned when using a Black Rapid strap while walking around.
I made the decision to bite the bullet and buy an authentic Nikon MB-D15. Adorama was my huckleberry, it arrived today...
Disclaimer: I'm not a product photographer, I don't have a studio, or proper lighting. My kitchen table was held hostage for the photo shoot.
My findings:
The Nikon unit is much nicer than the knockoff (KO). The buttons emulate the feel of the D7100 exactly. It doesn't rattle and the fit and finish is top notch (as one would expect).
The Nikon unit weighs 2oz more the the KO. It is also much sturdier.
You can squeeze the KO in the battery area and cause some significant deflection. The Nikon does not deflect at all.
The KO buttons work, but are not as sophisticated as the Nikon. The shutter release being the biggest difference.
The KO is also a bit larger then the Nikon and has a different profile for the bottom of the camera (I have tried to capture that in the photos).
The battery tray(s) from the KO will fit in the Nikon, although a little snug, the Nikon tray(s) will not seat all the way into the KO.
The Nikon is rock solid on the camera, it fits the camera perfectly and feels very good in the hand.

Overall, I very pleased with my decision to buy the OEM Nikon unit.
I Hope this helps some of you out there who are contemplating this purchase.
