Also I have only been reluctant to buy me this card because I do not know the manufacturer. But the reviews here have then convinced me to order the card. As always, a very fast delivery. Map unpacked, used in my Nikon D5100, recognized card, formatted card in the camera, made screen tests and deleted. All the best! Then, after about 34 shots (while on vacation), the message of the camera: The memory card must be formatted !! I have tried everything possible. The card is inserted into another Nikon and other Cameras and back home in the PC. Without Success. The images are lost. Fortunately, it happened at the beginning of the sailing vacation ..... My recommendation is: Better to rely on a Maken card. With the card brands, I then incidentally made 800 photos with no problems!
