For the price you will not lie, the product is excellent. From first glance a little cheap, the grip is none the less effective. The quality of the buttons is not the level of those on the device (unlike the official Nikon grip) but for the price we will not quibble, they do the work. Just a caveat on the battery housing that has a little game but is quickly forgotten. Remember to press the grip of the connector on the unit if the controls may not all function. Excellent grip for a very affordable price.
