I had bought a memory card for my Olympus C-750 and got a quick and easy genuine Olympus xD card sent. Unfortunately, this was not recognized by the camera: It is a formatting necessary but -mehrfach gestartet- regularly broke off with the message "Card error". I was informed by contact with the seller in UK (fast and friendly editing!) That my camera cards only to max. 512GB could read. A rescission of the purchase was offered to me immediately and was carried out as fast as non-bureaucratic. Hence my conclusion: Product ok, but unusable for me.
