Have exposed the very first day a stress test, but he has scanned the 200 pages without any problems. The quality of the scans I think is good, but I can not compare with other scans as this is my first scanner. The commissioning of the unit was unfamiliar to me. You have only to install the driver and a number of programs of which I really only use one of the included CD before connecting the scanner via USB cable to the computer. Practically is definitely that you do not need additional power cable. The use of the accompanying program is pretty self-explanatory, and after a few sample scans understandable even for beginners. Furthermore, the device is very small and takes up very little space away. All in all I am very satisfied with the scanner and can only recommend it.
