Summary: Waste of money! The load time for a single scan takes approximately 2 minutes. Why? I have no idea. The program interface is similar to the old gateway 1995 system and it has a tendency to crash. Not to mention after the 2 minutes of scanning the image may or may not appear on your desktop. - PLEASE LOOK FOR SOMETHING ELSE!
Summary: These scanners are great for older systems, because they are bus powered( through the USB cable ) the scanners may seem a little slow. The down fall is they do not work with Windows 7. There is a third party company that offers software and drivers (only works with their software at that time) but by the time you purchase the drivers and software you could have bought a current scanner. 39.99 for 1 year of updates or 79.99 lifetime updates.
Summary: relatively good quality considering the purchase price (+/-$45.00) It is easy to use. Had some issues with setting it up on my pc (win XP) which I found strange; but besides some minor issues, it has good/average scanning quality. Do not expect professional quality scans from this machine. Although the settings can be changed to achieve greater scanner resolution, it takes forever to scan a letter size document, and the end result is really not worth the output.
Summary: The scanner is small, light, easy to use, no power supply, it plugs directly to the laptop, definition is optimal. I don't know for professional results but for home work is a scanner that meets all your needs.
