Very good quality product. It can power the unit with either two batteries at once or LR6 batteries; the latter choice is very interesting in case the battery or batteries are depleted. All orders are transferred to the grip, allowing the shots "portrait" easier. These commands can be disconnected by an on / off button to avoid incorrect maneuvers. The grip of the camera is easy but requires some adaptation time to get used to the new format of the whole. Despite the price still Therefore, I advise this purchase ... Is also ideal for the EOS 500D !!!
