Personally, I think an original accessory / spare parts remains an original. Here agrees the quality and the good feeling to have that best possible accessories / spare parts to get back in the long run to be satisfied. Ok, the price is quite high, but that is yet to get over. A Top battery saving for a top camera, anything else would be at the wrong end. We trust many years Amazon, so we order original accessories only directly through Amazon and so have the certainty to obtain an original !!
