I use this with my Nikon D7000 and an off label battery.  This grip fits perfect, feels good in your hands, is exactly compatible with my camera, and looks just like the Nikon grip.  The wheel that you use to tighten works fine, but you can jiggle it back and forth.  This does not affect how it fits at all.  It doesn't mean that the grip is coming loose, its just how it is. It comes with an optional insert for AA batteries if you don't happen to have a second lithium battery charged.  I also like how it has the shutter button, AE-L/FE-L button, and front and rear dials as well as directional buttons to control the menus while the camera is vertical.I honestly did not know if it would be a fully compatible grip for that price but I was pleasantly surprised.  I definitely recommend this to anyone looking for a quality yet inexpensive grip.  It really gives your camera a professional look.
