As against the manual is more succinct. We must discover. Discovering that the flash memory of the device has only 30 megs, evening slide 12 to 5 megabytes, a red square indicates that the memory is full. Not explained also that there is only one USB port for scanning slides, unexplained need to put them in the difficult context crochet, for this purpose, then put in the live socket, scanned slides and to remove it and put it in the computer to save the photos and clear the memory, and thus start scanner 12 new slides. It is doable, but a little complicated. By cons congratulations for scanning pictures, in 3 seconds, they are scanned. and pretty. For movies, unfortunately frames are provided only for 24x36, I had pictures of a different format and hello difficult to put in the frame for film. The device is not really designed for that. For negative films 24x36; it's perfect. Finally for the price, this product is adequate, but we would have preferred at least 2 USB ports, one for scanner and to save in the computer.
