Summary: Unstable and the tech support stinks! I bought this a couple of years ago and really, really love it ... except when it doesn't work. They tell you to use the SF600_V3 driver with Windows 7, but when I run it I get the message "Not support this OS." So I have been using the SF600 that came with the scanner. But every 3 months, the scanner stops working. I reinstall the software and it still doesn't work. I have been wiping my computer, but tired of doing it.
Summary: I set this scanner up tonight and ran it through a few scenarios that I might run into. So far it scans pages really well and fast too. About 15-20 seconds for an 8.5" x 11.0" letter. It will scan checks and business cards too. Set up what a little strange. The packaged CD was the most up-to-date version of the driver that Genius has released so far so no complaints there.
