Very happy not to be having the phantom battery drain issues ...
I've had problems with aftermarket grips in the past on my other Nikon bodies, but I'm still not game for paying full price for a Nikon grip. This Vivitar has proved to be nearly flawless. All the function and dials are working and where they should be. I appreciate the accessory AF button on the grip, as well as the 8x AA battery capacity. It meshed a bit tight on its first uses, but as it will mostly live on the camera, and has gone on and off easier with time, I'm not worried about the fit. Very happy not to be having the phantom battery drain issues you see with some other aftermarket grips.
