Front off I am an amateur photographer and use them in my camera for about two months. An SD card of the highest class. First to look, she sees the silver stickers of very stylistic and elegant. Now the important part: I use them with my Kanera. Previously I had a Class 2 SD card. If you put after a Class 10SD card into the camera you notice immediately the difference. The transfer rate to the computer is fast enough. For me it has only 34 MB per sec. business, but is also completely in the green zone! Well done Sandisk. This SD card is recommended devenitiv!
