Teacher: Now, understand the problem? Solve this instance: I bought this for use in my Canon 40D and a SanDisk Ultra SD card. This CF to SD card reader does not work consistently. I am able to take a number of shots even at high rates without any trouble, look at the photos, download them, etc.. Then after a while the camera will say there is a CF error and I can't get it working anymore unless I: remove it, eject it from the CF to SD reader, then reinsert it. The SD card continues to work in other devices. After this happens once the card will take a few more pictures then fail completely and only a reformat will fix it. DO NOT BUY THIS CARD.
