I had some serious reservations about buying this, because I respect Nikon's quality and Vivitar has not been a significant brand since I was in high school (long ago!). But I am pleased that other reviews persuaded me to try it. It is nearly identical to my other Nikon battery grips, which cost 3 to 5 times as much. The rubberized surfaces are there, the controls integrate to the body, and it fits well. Under close examination the dials do not rotate as smoothly and the plastic housing seems a little thinner. But I am on a tight budget and have a two-day airshow coming, so up this may work out very well.
