after receiving the product, I set up the handle easily. I immediately noticed the very poor quality of production, and have compared it with that of a child's toy. The claws for holding the battery in place will barely maintain it. Moreover, after a short series of photos, where everything worked properly, my NIKON simply refused to function with this handle in place, telling me that I had to use compatible batteries (I had just placed the battery NIKON original inside, but he did not even want to, proving that this is indeed the handle is at issue, not the battery)
