Previously had another supposedly equivalent product (Transcend Ultimate 600x 32GB CompactFlash) purchased from Amazon for my photo safari guide which unfortunately after 3 days in the pants was because scrap. Have now resorted to more enterprises back on familiar brand quality back to where I was not disappointed. Whether at top speed in pictures Count Series Shoots Full HD or in fact the highest resolution, always top recording quality. So no error in the picture taken, or video footage. Map will not slow even at 90% charge capacity. Photos taken with Canon D7 incl. BG where it can not come to power shortage. This image sequences of up to the maximum number of Canon D7 with this CF card are possible. Also videos were clean stored and processed on the chip, even with a video snippet length of 40 minutes. Upload and download of data with this card is equal to the manufacturer's specifications. I give a 100% recommendation.
